In the name of Allah, the most Gracious, the most Merciful.

“O Allah, let Your mercy come upon Muhammad
and the family of Muhammad
as You let it come upon Ibrahim
and the family of Ibrahim
O Allah, bless Muhammad
and the family of Muhammad
as You blessed Ibrahim
and the family of Ibrahim.
Truly You are
Praiseworthy and Glorious.”

Note: 
Every 12 Rabiulawal (Islamic calendar-today), muslims around the world 

will commemorate the birth of the Prophet Muhammad (peace be upon him).
