Celebrating Milaad un Nabi
When we celebrate Milad, we gather, in order to send salutations (durud) to the Prophet (may Allah bless him and grant him peace), give charity to the poor (sadaqa), and to remember the wilada (birth) and virtues of the Prophet (may Allah bless him and grant him peace). The Ahl as-Sunna does not say that one must celebrate Milad only on the 12th of Rabi' al-Awwal; in fact it can be celebrated at any time of the year. Generally Milad an-Nabi is celebrated, on the 12th of Rabi' al-Awwal, by Muslims all over the world. In every Muslim country, there is a public holiday for Milad an-Nabi, except one country, but even in that country the people celebrate the Milad individually.
The birth of the anbiya has been mentioned in the Qur'an; for example, Adam, Musa, 'Isa, and Yahya (peace be upon them). Furthermore, if it is wrong to talk about the birth of the Prophet (may Allah bless him and grant him peace), then why has Allah Most High mentioned it in the Qur'an?
