What are hadiths about azan? Examples of hadiths about azan…
Ibn ʿUmar (ra) narrated that, “When the Muslims first arrived in Medina they used to assemble for the ritual prayer, and guess the approximate time for it. During those days, the practice of adhān for the prayers had not been introduced yet. One day they discussed the issue concerning a call for prayer. Some people suggested the ringing of a bell like the Christians, others proposed blowing a trumpet like the horn used by the Jews, but ʿUmar (ra) proposed using the (voice of a) man to call (the people) to the ritual prayer. Then, the Messenger of Allah (saw) said to Bilal, ‘O Bilal! Stand up and make the call for the ritual prayer!’”
