Hadith 666
Narrated Abdullah ibn Umar: The Prophet ﷺ said: Set the rows in order, stand shoulder to shoulder, close the gaps, be pliant in the hands of your brethren, and do not leave openings for the devil. If anyone joins up a row, Allah will join him up, but if anyone breaks a row, Allah will cut him off. Abu Dawud said: The name of Abu Shjrah is Kathir bin Murrah.
Hadith 732
The above mentioned tradition has also been reported by Muhammad bin Amr bin Ata through a different chain of narrators. This version adds: “When he prostrated himself he neither placed his arms on the ground nor closed them; putting forward his fingers towards the qiblah. ”
Hadith 964
Muhammad bin Amr bin Ata was sitting in the company of a few Companions of the Messenger of Allah ﷺ. He then narrated his tradition, but he did not mention the name of Abu Qatadah. He said: When he ( the Prophet) sat up the two rak’ahs he sat on his left foot; and when sat up after the last rak’ah he put out his left foot and sat on his hip.
