Salmah bin Shbyb سلمة بن شبيب · The Book on Salat (Prayer)

"I saw Allah's Messenger when he prostrated placing his knees (on the ground) before his hands, and when he got up, he raised his hands before his knees."

"Between the two prostrations, the Prophet would say: (Allahummaghfir li, warhamni, wajburni, wahdini, warzuqni). 'O Allah! Pardon me, have mercy on me, help me, guide me, and grant me sustenance.'"

he (Muhammad) said: "I heard him saying - while he was among ten of the Companions of the Prophet, one of whom was Abu Qatadah bin Ribi."
