أَفَحُكْمَ ٱلْجَٰهِلِيَّةِ يَبْغُونَ ۚ وَمَنْ أَحْسَنُ مِنَ ٱللَّهِ حُكْمًۭا لِّقَوْمٍۢ يُوقِنُونَ
Is it a judgment of the time of (pagan) ignorance that they are seeking? Who is better than Allah for judgment to a people who have certainty (in their belief)?

Merits of the Helpers in Madinah (Ansaar)
Chapter: The merits of Al-Ansar
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."
