Hadith.997 - Al-Halabi narrated from Imam Jafar ibn Muhammad Al-Sadiq (as) that He said:
"In the two prostrations of forgetfulness, you should say
Bismillah wa billah, wa salla Allahu ‘ala Muhammad wa Aali Muhammad
In the name of Allah and by Allah, and may Allah send blessings upon Muhammad and the family of Muhammad.
He said: "And I heard him say another time:
Bismillah wa billah, as-salamu ‘alayka ayyuhan-nabiyyu wa rahmatullahi wa barakatuh
In the name of Allah and by Allah, peace be upon you, O’ Prophet, and the mercy of Allah and His blessings.”
