Salam Alaik Ya Shuyukh,
What’s the opinion of Mawlid of Nabi Muhammad saw in all four Madzhab of Ahl Sunnah? Some Ulama’ said that it is haram to celebrate birthdays including also the Prophet’s saw birthday while some say it is allowed as bringing us closer to know our Sayyidina al Amin and remember him by doing salawat and also Qasidas.
wa `alaykum salam,
In a hadith in Sahih Muslim we find a hadith wherein Muhammad (saws) was asked as to why he fasted on Mondays. He (saws) responded that,”this was the day of his birth and that he fasted on it as a way of thanking Allah (swt).” Therefore, it can be established that celebrating his blessed birth was in fact a Sunnah of Rasuulullah (saws).
