Abu Umayr bin Anas bin Malik reported,

One of his paternal uncles from the Ansar reported that the Prophet ﷺ was concerned about the prayer and how to gather the people for it.It was suggested to him, "Raise a banner when the time of prayer arrives, and when the people see it, they will inform one another." But this did not please him.Then the qun was mentioned to him, meaning the horn. Ziyad said it was the horn of the Jews. This did not please him either, and he said, "It is something belonging to the Jews."Then the bell was mentioned to him, but he said, "It is something belonging to the Christians."Abdullah bin Zayd bin Abd Rabbih left, sharing the concern of the Messenger of Allah ﷺ, and the call to prayer was shown to him in a dream. The next morning he came to the Messenger of Allah ﷺ and informed him, saying, "Messenger of Allah, I was between sleep and wakefulness when someone came to me and showed me the call to prayer."Umar bin Khattab had already seen it before that, but had kept it to himself for twenty days. He then informed the Prophet ﷺ, who said to him, "What prevented you from telling me?"He replied, "Abdullah bin Zayd preceded me, so I felt too embarrassed to mention it."The Messenger of Allah ﷺ said, "Bilal, get up and do what Abdullah bin Zayd tells you to do."So Bilal made the call to prayer.Abu Bishr said, Abu Umayr informed me that the Ansar claim that had Abdullah bin Zayd not been ill on that day, the Messenger of Allah ﷺ would have made him the muezzin.

حدثنا عباد بن موسى الختلي وزياد بن أيوب وحديث عباد أتم قالا حدثنا هشيم عن أبي بشر قال زياد أخبرنا أبو بشر

عن أبي عمير بن أنس

عن عمومة له من الأنصار قال اهتم النبي ﷺ للصلاة كيف يجمع الناس لها فقيل له انصب راية عند حضور الصلاة فإذا رأوها آذن بعضهم بعضا فلم يعجبه ذلك قال فذكر له القنع يعني الشبور وقال زياد شبور اليهود فلم يعجبه ذلك وقال هو من أمر اليهود قال فذكر له الناقوس فقال هو من أمر النصارى فانصرف عبد الله بن زيد بن عبد ربه وهو مهتم لهم رسول الله ﷺ فأري الأذان في منامه قال فغدا على رسول الله ﷺ فأخبره فقال له يا رسول الله إني لبين نائم ويقظان إذ أتاني آت فأراني الأذان قال وكان عمر بن الخطاب رضي الله عنه قد رآه قبل ذلك فكتمه عشرين يوما قال ثم أخبر النبي ﷺ فقال له ما منعك أن تخبرني فقال سبقني عبد الله بن زيد فاستحييت فقال رسول الله ﷺ يا بلال قم فانظر ما يأمرك به عبد الله بن زيد فافعله قال فأذن بلال قال أبو بشر فأخبرني أبو عمير أن الأنصار تزعم أن عبد الله بن زيد لولا أنه كان يومئذ مريضا لجعله رسول الله ﷺ مؤذنا
