"I said: 'O Messenger of Allah (S.A.W), make me the Imam of my people.' He said: 'You are their Imam, so consider the weakest among them and choose a Mu'adhdhin who does not accept any payment for his Adhan.'"
Sunan an-Nasa'i Book 7, Hadith 47
← Previous Hadith "If the people knew what (virtue) there is in the call to prayer and the first row, and they had no other way but to draw lots concerning them, they would draw lots. If they knew what (virtue) there is in coming early for the prayer, they would compete in doing so. And if they knew what (virtue) there is in 'Atamah and Subh prayer, they would come even if they had to crawl."
