It is narrated from Sayyiduna Abd al-Rahman bin Awf (may Allah be pleased with him) that he said: The Messenger of Allah (peace and blessings be upon him) missed one of his Companions and said: "Where were you? I did not see you. Did you not attend the prayer?" He said: Of course I did, but I came when the people had already settled in their rows, and I disliked stepping over the people's necks. He (peace and blessings be upon him) said: "You did well."
