The minimum that suffices in bowing and prostration

A man of Madinah reports that the daughter of Sayyiduna Sa'd (may Allah be pleased with him) used to make a strange effort to bend excessively in ruku'. Sa'd said to her: "It is enough for you to place your hands on your knees."

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said: When a man places his hands on his knees in ruku', and his forehead on the ground in sajdah, these pillars are fulfilled.

Muhammad bin Ali said: Placing one's hands on the knees in ruku', and placing one's forehead on the ground in sajdah, fulfils these pillars.

Sayyiduna Ibn Umar (may Allah be pleased with them both) said: When a man places his forehead on the ground, that suffices.

Ibn Sirin said: If in bowing he places his hands on his knees, and in prostration he places his forehead on the ground, then these pillars have been fulfilled.

Ya'la bin Hakim said: Tawus and Ikrimah said, and I think Ata was the third of them: When he has placed his forehead on the ground, he has fulfilled what is obligatory.

Musayyib bin Rafi' said: When he has placed his forehead on the ground, the obligation has been fulfilled.

Ma'qil bin Ubaydullah said: I asked Ata about the minimum extent of bowing and prostration, and he said: When he has placed his forehead on the ground and his hands on his knees, these pillars have been fulfilled.

Mujahid said: When he has placed his hands on his knees, the bowing is done.
