Another trick (Irony) that opposition use to attain is saying that some ignorant people have invent this all and It was never ever celebrated before in previous ages and etc. Let them have some glimpses of facts from the very true history.

..:: History of Celebrating Mawlid an-Nabi Sallallaho Alaihi wa Sallam ::..

1. Hadrat Allama Mulla Ali Qari saying the routine of the people of Madina Munawwarah writes,

“The people of Madina Munawwarah (May ALLLAH have Mercy on them) used to arrange and attend mawlid gatherings with enthusiasm and sincerity on the occasion of Mawlid Sharif.” (Mawrid ar-Riwa Fi Mawlid an-Nabawi, Page 29)

2. Ibne Jauzi says:

“Fala Zaala Ahlul Haramain ash-Shareefain Wal Misr, Wal Yemen, Wash Shaam Wa Saa’iri Bilaadil Arabi Minal Mashriqi Wal Maghribi Yahtafiloona Bimajlisi Maulidin Nabiyyi Alaihis Salaatu Was Salaam Wa Yafrahoona Biqudoomi Hilaali Rabi’il Awwali Biharkati Maulidin Nabiyyi (Sallallahu Alaihi wa Sallam)”.

“People of Haramain Shareefain (Makkah and Madinah) and Egypt and Yemen and Syria and of the eastern and western cities of Arabia hold functions in celebration of the birth of the Prophet (Sallallahu Alaihi wa Sallam), rejoice at the sighting of the Rabi-ul-Awwal moon, bathe and put on their best dresses adorn themselves in various ways, put on scent, and give alms with great joy, and exert themselves in listening to the Milad of the Prophet (Sallallahu Alaihi wa Sallam). By doing so, they themselves attain to success, as it has been proved that by celebrating the Milad of the Prophet (Sallallahu Alaihi wa Sallam) much good accrues the whole year round: security and comfort, greater means of livelihood, increase in children and in wealth, peace in cities and contentment and peace in homes”

In Haramayn (i.e. Makkah Mukarrama and Madina Munawwarah), in Egypt, Yemen rather all people of Arab world have been celebrating Mawlid for long. Upon sight of the moon in Rabi ul Awwal their happiness touches the limits and hence they make specific gatherings for Dhikr of Mawlid due to which they earn immense Ajr and Success. (Biyan al Milaad an Nabwi, Page No. 58)

10. Shah Waliullah Muhadith Dhelvi mentions one of his all time wonderful experiences as:

I took part in a gathering of Mawlid inside Makkah where people were sending Darood and Slaam upon Prophet (Peace be upon him) and mentioning the incidents which took place during the time of your birth (before and after) and those which were witnessed before you were appointed as a Nabi (such as Noor eliminating from Bibi Amina Radi ALLAHu Ta’ala Anha, she seeing Noor, woman proposing to Syeduna Abdullah Radi ALLAHu Ta’ala Anho on sight of Noor on his forhead etc…) suddeny I saw Noor to have enveloped one group of people, I don’t claim that I saw this with my bodlily eyes, nor do I claim that it was spiritual and Allah knows the best regarding these two, however upon concentration on these Anwaar a reality opened upon me that these Anwaar are of those Angels who take part in such gatherings, I also saw Mercy to be decending along with Anwaar of Angels. (Fayudh al Haramayn, Pages 80-81)

11. Sheikh ul Islam Imam Ibn Hajr al Haytami (Rahimuhullah) writes:

The gatherings of Mawlid and Adhkaar which take place during our time, they are mostly confined to good deeds, for example in them Sadaqat are given, Dhikr is done, Darud and Salam is sent upon the Prophet (Sallallaho Alaihi wa Sallam) and he is praised. (Fatawa al Hadithiyyah, Page No. 202)
