Yahya related to me from Malik from Ishaq ibn Abdullah ibn Abi Talha that Anas ibn Malik heard Umar ibn al-Khattab return the greeting of a man who greeted him. Then Umar asked the man, "How are you?" He said, "I praise Allah to you." (Ahmadu ilayka Allah) Umar said, "That is what I wanted from you."

← Previous Hadith Yahya related to me from Malik from Ishaq ibn Abdullah ibn Abi Talha from Abu Murra, the mawla of Aqil ibn Abi Talib from Abu Waqid al-Laythi that the Messenger of Allah, may Allah bless him and grant him peace, was sitting in the mosque with some people when three people came in. Two came toward the Messenger of Allah, may Allah bless him and grant him peace, and one went away. When the two stopped at the assembly of the Messenger of Allah, may Allah bless him and grant him peace, they gave the greeting. One of them saw a gap in the circle and sat in it. The other sat down behind the circle. The third turned away and left. When the Messenger of Allah, may Allah bless him and grant him peace, finished, he said, "Shall I tell you about three people? One of them sought shelter with Allah, so Allah gave him shelter. The other was shy, so Allah was shy to him. The other turned away, so Allah turned away from him."

Muwatta Malik Book 53, Hadith 4 Next Hadith → Yahya related to me from Malik from Ishaq ibn Abdullah ibn Abi Talha that at-Tufayl ibn Ubayy ibn Kab told him that he visited Abdullah ibn Umar one morning and went out with him to the market, and when they were out, Abdullah ibn Umar did not pass by anyone selling poor merchandise or selling commodities or a needy person or anyone but that he greeted them.

At-Tufayl said, "I came to Abdullah ibn Umar one day and he asked me to follow him to the market. I said to him, 'What will you do in the market if you will not stop to sell nor seek any goods or barter with them or sit in any of the assemblies or market?' Abdullah ibn Umar said that we should sit down and talk, and then he explained, 'Abu Batni, (lit. father of the belly, at- Tufayl had a prominent stomach), we go out in the morning only for the sake of the greeting. We greet whomever we meet.' "
