It is narrated from Muhammad bin Amr bin Ata' that we were present in a gathering of the Companions of the Messenger of Allah (peace and blessings be upon him). We discussed the prayer of the Messenger of Allah (peace and blessings be upon him), and Abu Humayd al-Sa'idi (may Allah be pleased with him) said: I remember the prayer of the Messenger of Allah (peace and blessings be upon him) best of you all. Then he mentioned the complete hadith. In it there is also that when he prostrated, he placed his hands in such a way that they were neither spread out too much nor drawn in completely, and the tips of the toes of his feet were also facing the qiblah.
