So the days when Anbiya are born are days of Salam in sight of Allah.

Proof No. 4 Quran states:

We sent Moses with Our signs (and the command). "Bring out thy people from the depths of darkness into light, and teach them to remember the “Days of Allah (بِأَيَّامِ اللَّهِ)." Verily in this there are Signs for such as are firmly patient and constant,- grateful and appreciative. (14:5)

What are the Ayyam of Allah? Imam Baihaqi narrates in his Shuyab ul Iman that Prophet (saw) said: The Days of Allah are his blessings and Signs [Tafsir Ruh ul Ma’ani under 14:5]

Istadlal from Sahih Ahadith

Proof No.1

Book 006, Number 2606 (Sahih Muslim)

Abu Qatada Ansari (Allah be pleased with him) reported that Allah's Massenger (may peace be upon him) was asked about fasting on Monday, whereupon he said: It is (the day) when I was born and revelation was sent down to me.


This Hadith is also reported in by Imam Bahayqi in his “Sunnan ul Kubra” (vol. 4, pg. 300 Hadith no 8182, 8259), in the “Sunan” of Imam Nisai and the “Musnad” of Imam Ahmad bin Hanbal.

It is clear from this Hadith that the Holy Prophet (saw) was very happy about the day of his birth and so fasted out of gratitude. Fasting is a form of worship, so one can celebrate this day by any form of ibada. One can fast or hold gatherings or provide food to the poor, all being acts of worship.


Proof No.2

Volume 7, Book 62, Number 38: (Sahih Bukhari)

Narrated 'Ursa; Thuwaiba was the freed slave girl of Abu Lahb whom he had manumitted, and then she suckled the Prophet. When Abu Lahb died, one of his relatives saw him in a dream in a very bad state and asked him, "What have you encountered?" Abu Lahb said, "I have not found any rest since I left you, except that I have been given water to drink in this (the space between his thumb and other fingers) and that is because of my manumitting Thuwaiba."

Abu Lahab freed Thuwaiba on joy at birth of Prophet (salallaho alaihi wasalam), even the worst of Kufaar and greatest of enemies is given relaxation in his Adhaab due to freeing Thawaiba by pointing with his finger, so Imagine the situation of a momin who rejoices on Mawlid, detailed explanation of this hadith shall be given in the last section of Verdicts from classical scholars.

Proof No.3

In Sahih Muslim, Volume 2, Page No. 147, Hadith No. 1130 (Dar ul Kutab al ILmiyyah)

Ibn Abbas “Allah be pleased with him” reported: The Prophet “Allah’s blessing and peace be upon him” came to Madina and saw the Jews fasting on the tenth day of Muharram. They were asked about that. They replied: “This is the day, on which Allah made Moses and the children of Israel emerge victorious over Pharoah. So, we fast on it “OUT OF GLORIFICATION TO IT”. The Prophet “Allah’s blessing and peace be upin him” said: “We have more claim over Moses than you.” So, he ordered Muslims to fast on it

If Jews glorify their days to venerate Musa (a.s) then we Muslims have more right to venerate and rejoice on day when Prophet (saw) was born, this is an accepted analogy as Ulama have derived this specific ruling from the hadith, which shall be mentioned in the last section with detail.


Proof No.4

[Sunnan an Nasai’I, Volume 1, Page No. 450, Hadith No. 450]

Hadrat Anas bin Malik (ra) narrates that Prophet (saw) while mentioning his journey of Miraaj said: Jibril (a.s) asked me to get off from Baraak at Bethlehem and told me to say the prayer there, after which he said: Do you know where you have prayed (O Messenger of Allah)? You prayed at Bethlehem where Isa (a.s) was born.

So the Mawlid, the places where Prophets(A.S) are born are amongst Sha’ir (sings to be venerated) of Allah.

So here Allah himself says to Rejoice and be happy on such a day , As its Sunnah of friends of Shatan [devil] to cry on such a day.

:: Sayings of the Great Scholars about Celebrating Mawlid? ::..

Hazrat Maulana Shah Abdul Haq Dehlvi

1. After relating Abu Lahab’s relief on setting Thuwaibha free, Hazrat Maulana Shah Abdul Haq Dehlvi in his famous book Madarijun Nabuwwat says:

"This event provides a clear proof to those who celebrate Meelaad Shareef by rejoicing and alms giving on the night of the birth of the holy Prophet (Sallallahu Alaihi wa Sallam), People of Makkah gather on 12th Rabi-ul-Awwal to is it the house in which the Prophet (Sallallahu 'Alaihi Wa Sallam) only because he was his nephew, he has been receiving, in spite of this being an idolater, the benefits of thus rejoicing in his grave every Monday, then how much more blessing will fall to the lot of him who acknowledges the Prophet (Sallallahu Alaihi wa Sallam) as the beloved of ALLAH and His true Prophet, and celebrates Meelaad Shareef repeatedly.”

As the poet says:

Dostaan Ra Kujaa Kunee Mahroom
Tu Keh Ba Dushmanaan Nazar Daree

How would you (Sallallahu 'Alaihi Wa Sallam) leave out friends?
You, who feel great compassion, even for your enemies."

Imaam Qastalaani

2. Due to the rejoicing he made at the birth of the holy Prophet (Sallallahu Alaihi wa Sallam) imam qastalaani says:

"How would anyone of the Ummah the holy Prophet (Sallallahu Alaihi wa Sallam) fare, who is a Muslim and is steadfast in his belief in the unity of Allah and rejoices at his (Sallallahu Alaihi wa Sallam) birth and who spends whatever he can afford for the love of him (Sallallahu Alaihi wa Sallam)? I swear by my life, that Allah, out of His Grace, will not reward such a person but by entering him into the Gardens of Bliss.” (Mawaahib-dunniyah by Imam Qastalani, Vol1, Page 27, Published in Egypt)

3. Imaam Qastalaani says:

"May ALLAH bless a person who celebrates ‘Eid’ on the nights of the blessed month of the holy birth of the Prophet (Sallallahu Alaihi wa Sallam), so that it hurts them the most who have a serious disease in their hearts and who suffer from an incurable ailment on account of the blessed birth".,. (Mawaahib-dunniyah by Imam Qastalani, Vol1, Page 27, Published in Egypt)

4. Imaam Qastalaani further says that How blessed is the month in which the Prophet of ALLAH (Sallallahu Alaihi wa Sallam) was born! How very superior and sacred! How very respected the nights (of the month) as though they are pearls shining bright throughout the ages! How full of light and pure the face of the one born! How blessed the Being (ALLAH) who made the birth of the holy Prophet (Sallallahu Alaihi wa Sallam) a springtime for the hearts and his (Sallal Laahu 'Alaihi Wa Sallam) face a manifestation of splendor!., ,

Wa Qaulul Haqqi Ya'zabu Lis Samee'ee

And, O questioner! If you want to know about my attributes and my affairs, I would say this:

Fawajhi Waz-Zamaanu Wa sharu Wad'ee

My face and my age and the month of my birth is springtime in the month of Rabee-ul-Awwal.

Rabee'un Fi Rabee 'in Fi Rabee'ee

Ibne Jauzi views
has devoted a whole book to Meelaad, which is called "Maulad-ul-Uroos". Allamah Ibne Jauzi says:

"And whosoever rejoices at the birth of our beloved Mustafa (Sallal Laahu 'Alaihi Wa Sallam), this rejoicing by him will turn the Fire away, and whosoever spends even a dirham on the occasion of the Meelaad of the Prophet of ALLAH (Sallal Laahu 'Alaihi Wa Sallam) he (Sallallahu Alaihi wa Sallam) will intercede on his behalf and his intercession will be accepted"
(Meelad-ul-Uroos, Page 9)

7. And, Ibne Jauzi has also written:
"O Meelaad of the Prophet (Sallallahu Alaihi wa Sallam)! You are mightily praised, and the praise is such that it is the loftiest and the remembrance is such that it is the most excellent; how I wish the remembrance of the holy Prophet (Sallallahu Alaihi wa Sallam) shall be with me for a long time! How I wish his (Sallallahu Alaihi wa Sallam) Meelaad shall be with me for a long time!”..

(Meeladul Uroos, Page 28)

8. In this regard, Hazrat shah Waliullah [rah] says:

"Following the ancient practice, I recited the Holy Qur'aan and distributed the things (food etc.) Of the Niyaaz (Faatihah) of the Prophet (Sallallahu Alaihi wa Sallam) and made a public display of his blessed heir (Moo'e Muboarak). While reciting (the Holy Qur'aan), Mala'i A'la (Angels nearest to ALLAH) came to attend the Mahfil-e-Meelaad and the blessed soul of the Prophet (Sallallahu Alaihi wa Sallam) showed much kindness to me (Shah Waliyul Laah) and my friends. I, thus, saw that Mala'i A 'la (Angels nearest to ALLAH) and, with them, the whole group of Musalmaans, were ascending to high heaven (on account of the blessings of the Prophet) and this blessed condition was reflected (in the Mahfil-e-Meelaad)."

9. Hazrat Shah Abdul Haq Muhaddis Dehlvi (may Allah have mercy on him), in his book "Ma Sabata Minas Sunnah" referring to the night of the blessed birth, of the holy Prophet (Sallal Laahu 'Alaihi Wa Sallam) says:

10. Those calling themselves followers of Shah Waliyyullah's family should also note the following statement of Hazrat Shah Waliyyullah Muhaddis Dehlvi. In his book, "Ad Durrus Sameen", he says:

"My dear father, Hazrat Shah Abdur Raheem Dehlvi (may ALLAH have mercy on him) informed me that he used to get food cooked on Meelaad days as a mark of rejoicing for him (Sallallahu Alaihi wa Sallam). One year it so happened that he could not afford anything except roasted grams, so he distributed those among the people, with the result that he had a vision of the holy Prophet (Sallallahu Alaihi wa Sallam) in his dream and saw that those roasted grams were lying before him (Sallal Laahu Alaihi Wasallam) and he (Sallallahu Alaihi wa Sallam) looked pleased".

(Ad Durrus Sameen, Page 3)

Haji Imdadullah Sahib Muhajir Makki (may ALLAH have mercy on him) says:

"The practice of this faqeer has been that I participate in Meelaad Shareef functions. In view of the fact that doing so brings blessings, I myself hold Meelaad every year, and find great solace and joy in Qiyaam (reciting salutations in a standing position)"....

Maulana Shaikh Abdul Haq Muhaddis Allahabaadi

12. In the fourth chapter of his book "Ad Durrul Munazzam", Maulana Shaikh Abdul Haq Muhaddis Allahabaadi has recorded in detail incidents which manifested themselves at the time when the holy Prophet (Sallallahu Alaihi wa Sallam) was born. These include:

"A cluster of stars concentrated over the roof of his house at the time of the birth of the holy Prophet (Sallal Laahu 'Alaihi Wa Sallam); Angels hoisted flags on holy Baitul Laah and in the east and in the west; the whole atmosphere was filled with the voices of Angels and houries reciting salutations to him in the standing position and congratulating each other and rejoicing with abandon; animals also congratulated each other at the birth of the holy Prophet (Sallallahu Alaihi wa Sallam), the Ka'batul Laah bowed in a manner of saluting, and the falsehood vanished and the light of truth spread light in all directions."

To celebrate Mawlid is amongst the great tributes to Prophet (Salallaho Alaihi wa Sallam), but the condition is that it should be clear of evil things. Imam Suyuti has said: It is Mustahab for us to be happy on birth of Prophet (Salallaho Alaihi wa Sallam)
