al-Husain bin Hryth الحسين بن حريث · The Book of Forgetfulness (In Prayer)

"The Messenger of Allah (ﷺ) sent me on an errand then I came back to him while he was praying. I greeted him with the salam and he gestured to me. When he finished he called me and said: 'You greeted me with Salam just now and I was praying.' And he was facing toward the east that day."

"Aishah said: 'Turning around during prayer is something that the Shaitan snatches from one's prayer.'"

"We used to speak to each other during the prayer, saying whatever was necessary, at the time of the Messenger of Allah (ﷺ), until this verse was revealed: Guard strictly (five obligatory) As-Salawat (the prayers) especially the middle Salah (i.e. the best prayer- 'Asr). And stand before Allah with obedience (and do not speak to others during the Salah (prayers)), so we were commanded to be silent."
