The Prophet (Sal Alaahu alaihi wa Sallam) said:
Whoever sends blessings on me ten times in the morning and
ten times in the evening will obtain my intercession (Shafa’
ah) on the Day of Judgment.
Allaahumma salli wa sallim ‘alaa Nabiyyina Muhammadin
O Allaah, we for your peace and blessings upon our Prophet Muhammad.
