What did Anas tell Ghailan bin Jarir about the Ansar and the tribe of Al-Azd that Prophet Muhammad (saw) praised?
 Narrated Ghailan bin Jarir:                     I asked Anas, "Tell me about the name 'Al-Ansar.; Did you call yourselves by it or did Allah call you by it?" He said, "Allah called us by it." We used to visit Anas (at Basra) and he used to narrate to us the virtues and deeds of the Ansar, and he used to address me or a person from the tribe of Al-Azd and say, "Your tribe did so-and-so on such-and-such a day."
