Chapter: To prostrate on seven bones

The Prophet (ﷺ) was ordered (by Allah) to prostrate on seven parts and not to tuck up the clothes or hair (while praying). Those parts are: the forehead (along with the tip of nose), both hands, both knees, and (toes of) both feet.

The Prophet (ﷺ) said, "We have been ordered to prostrates on seven bones and not to tuck up the clothes or hair."

(He was not a liar) We used to pray behind the Prophet (ﷺ) and when he said, "Sami`a l-lahu liman hamidah", none of us would bend his back (to go for prostration) till the Prophet (ﷺ) had placed his, forehead on the ground.
