question #3 Sahih Muslim 824c, Book 6, Hadith 346 : What role did the city of Kufa play in the preservation and transmission of Quranic recitation?

I met Abu Darda’, and he said to me: To which country do you belong? I said: I am one of the people of Iraq. He again said: To which city? I replied: City of Kufa. He again said: Do you recite according to the recitation of ‘Abdullah b. Mas’ud? I said: Yes. He said: Recite this verse (By the night when it covers) So I recited it: (By the night when it covers, and the day when it shines, and the creating of the male and the female). He laughed and said: I have heard the Messenger of Allah (ﷺ) reciting like this.
