Hisham bin 'Urwa هشام بن عروة · The Book on Salat (Prayer)

"Allah's Messenger would say one Taslim for the Salat while facing forward and turning to his right side a little."

Allah's Messenger performing Salat in the house of Umm Salamah wrapped in one garment.

Allah's Messenger said: "Perform Salat in sheep pens but do not perform Salat in the camels' resting area."

Allah's Messenger said: "When one of you is sleepy and he is performing Salat, then let him lie down until the sleep is gone from him. For when one of you performs Salat while he is sleepy, perhaps he wants to seek forgiveness but he curses himself."
