(185) باب الصَّلاَةِ عَلَى النَّبِيِّ صلى الله عليه وسلم بَعْدَ التَّشَهُّدِ
Abu Humaid al-Said said:
Some people asked: Messenger of Allah, how should we invoke blessings on you? He said: Say," O Allah, bless Muhammad, his wives and his off springs, as Thou didst bless Abraham's family, and grant favours to Muhammad's family, his wives and off springs, as Thou didst grant favours to Abraham's family. Thou art indeed praiseworthy and glorious.
