Bright proof For Celeberating Mawlid

"A scholar from Medina came to the Sudan. The people of Sudan said to him: 'We celebrate the Mawlid of the Prophet (may Allah bless him and his family and grant them peace) every year, and we want to ask you for an evidence for this.' He said: 'Your evidence is right in front of you, and you hear it every hour! Allah (most high) said, {And all We relate to you of the stories of the Messengers is that with which We make your heart firm} (11:120) So if the life stories of the Messengers and their news make firm the heart of the master of the messengers and of all the worlds, how could the memory and mention of the birth of the Prophet (may Allah bless him and his family and grant them peace) not make firm the hearts of the Muslims?" - Shaykh Salih al-Ja'fari, The Friday Lessons, vol 8, p. 21.
