Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates from Sayyiduna al-Agharr al-Muzani (may Allah be pleased with him) that he said: "The Messenger of Allah (peace and blessings be upon him) had assigned me a quantity of dates owed by a man of the Ansar, but he kept putting me off in paying it. I spoke to the Messenger of Allah (peace and blessings be upon him) about it, and he (peace and blessings be upon him) said: 'O Abu Bakr! Go with him tomorrow morning and get his dates for him.' He said: Sayyiduna Abu Bakr (may Allah be pleased with him) promised to meet me at the mosque when we had prayed the morning prayer. I found him where he had promised me, and we set off. On the way, whenever someone saw Sayyiduna Abu Bakr (may Allah be pleased with him) from a distance, he would greet him (first). Then Sayyiduna Abu Bakr (may Allah be pleased with him) said (to me): 'Do you not see how much virtue these people are gaining over you (by greeting first)? Let no one get ahead of you in giving the greeting of peace.' He said: (After that,) whenever someone appeared before us, we would hasten to greet him before he could greet us."
No one narrated this hadith from Nafi' (may Allah have mercy on him) except Muhammad bin Ishaq (may Allah have mercy on him), and Salamah bin al-Fadl (may Allah have mercy on him) is alone in narrating it from him.
