AbuUmayr reported on the authority of his uncle who was from the Ansar (the helpers of the Prophet): The Prophet ﷺ was anxious as to how to gather the people for prayer. The people told him: Hoist a flag at the time of prayer; when they see it, they will inform one another. But he (the Prophet) did not like it. Then someone mentioned to him the horn. Ziyad said: A horn of the Jews. He (the Prophet) did not like it. He said: This is the matter of the Jews. Then they mentioned to him the bell of the Christians. He said: This is the matter of the Christians. Abdullah ibn Zayd returned anxiously from there because of the anxiety of the Apostle ﷺ. He was then taught the call to prayer in his dream. Next day he came to the Messenger of Allah ﷺ and informed him about it. He said: Messenger of Allah, I was between sleep and wakefulness; all of a sudden a newcomer came (to me) and taught me the call to prayer. Umar ibn al-Khattab had also seen it in his dream before, but he kept it hidden for twenty days. The Prophet ﷺ said to me (Umar): What did prevent you from saying it to me? He said: Abdullah ibn Zayd had already told you about it before me: hence I was ashamed. Then the Messenger of Allah ﷺ said: Bilal, stand up, see what Abdullah ibn Zayd tells you (to do), then do it. Bilal then called them to prayer. AbuBishr reported on the authority of AbuUmayr: The Ansar thought that if Abdullah ibn Zayd had not been ill on that day, the Messenger of Allah ﷺ would have made him mu'adhdhin.  

اهْتَمَّ النَّبِيُّ ﷺ لِلصَّلاَةِ كَيْفَ يَجْمَعُ النَّاسَ لَهَا فَقِيلَ لَهُ انْصِبْ رَايَةً عِنْدَ حُضُورِ الصَّلاَةِ فَإِذَا رَأَوْهَا آذَنَ بَعْضُهُمْ بَعْضًا فَلَمْ يُعْجِبْهُ ذَلِكَ قَالَ فَذُكِرَ لَهُ الْقُنْعُ يَعْنِي الشَّبُّورَ وَقَالَ زِيَادٌ شَبُّورَ الْيَهُودِ فَلَمْ يُعْجِبْهُ ذَلِكَ وَقَالَ هُوَ مِنْ أَمْرِ الْيَهُودِ قَالَ فَذُكِرَ لَهُ النَّاقُوسُ فَقَالَ هُوَ مِنْ أَمْرِ النَّصَارَى فَانْصَرَفَ عَبْدُ اللَّهِ بْنُ زَيْدِ بْنِ عَبْدِ رَبِّهِ وَهُوَ مُهْتَمٌّ لِهَمِّ رَسُولِ اللَّهِ ﷺ فَأُرِيَ الأَذَانَ فِي مَنَامِهِ قَالَ فَغَدَا عَلَى رَسُولِ اللَّهِ ﷺ فَأَخْبَرَهُ فَقَالَ لَهُ يَا رَسُولَ اللَّهِ إِنِّي لَبَيْنَ نَائِمٍ وَيَقْظَانَ إِذْ أَتَانِي آتٍ فَأَرَانِي الأَذَانَ قَالَ وَكَانَ عُمَرُ بْنُ الْخَطَّابِ ؓ قَدْ رَآهُ قَبْلَ ذَلِكَ فَكَتَمَهُ عِشْرِينَ يَوْمًا قَالَ ثُمَّ أَخْبَرَ النَّبِيَّ ﷺ فَقَالَ لَهُ مَا مَنَعَكَ أَنْ تُخْبِرَنِي فَقَالَ سَبَقَنِي عَبْدُ اللَّهِ بْنُ زَيْدٍ فَاسْتَحْيَيْتُ فَقَالَ رَسُولُ اللَّهِ ﷺ يَا بِلاَلُ قُمْ فَانْظُرْ مَا يَأْمُرُكَ بِهِ عَبْدُ اللَّهِ بْنُ زَيْدٍ فَافْعَلْهُ قَالَ فَأَذَّنَ بِلاَلٌ قَالَ أَبُو بِشْرٍ فَأَخْبَرَنِي أَبُو عُمَيْرٍ أَنَّ الأَنْصَارَ تَزْعُمُ أَنَّ عَبْدَ اللَّهِ بْنَ زَيْدٍ لَوْلاَ أَنَّهُ كَانَ يَوْمَئِذٍ مَرِيضًا لَجَعَلَهُ رَسُولُ اللَّهِ ﷺ مُؤَذِّنًا

"عَنْ عَبْد الرَّحْمن بن أَبى لَيْلَى: أَنَّ رسُولَ اللَّهِ ﷺ اهْتَمَّ للِصَّلَاةِ كَيف يَجْمَع الناس لَهَا؟ فَقَالَ: لَقَد هَممَتُ أَنْ أَبْعَثَ رِجَالًا فَيَقُومُ كُلُّ رجُلٍ مِنْهُم عَلَى أَطَمٍ مِنْ آطَامِ المدِينَة فَيُؤْذِنُ كُل مِنْهُم مَنْ يَلِيهِ، فَلَم يُعْجِبهُ ذَلِكَ، فَذَكَرُوا لَهُ النَّاقُوسَ فَلَمْ يُعْجِبهُ ذَلِكَ، فَانْصَرفَ عَبْدُ اللَّهِ بن زَيْد مهتمًا لهم رَسُولِ اللَّهِ ﷺ فَأُرِى الأذَان في مَنَامِهِ، فَلَمَّا أَصْبَحَ غَدَا فَقَالَ: يَا رَسُولَ اللَّهِ! رَأَيْتُ رَجُلًا عَلَى سَقْفِ المَسْجِدِ وَعَلَيْه ثَوْبَانِ أَخْضَرَانِ يُنَادِى بِالأَذَانِ، فَزَعَمَ أَنَّهُ أَذَّنَ مَثْنَى مَثْنَى الأَذَان، فَلَمَّا فَرَغَ قَعَدَ قَعْدةً ثُمَّ عَادَ فَقَالَ مِثْلَ قَوْلِهِ الأَوَّلِ، فَلَمَّا بَلَغَ حَىَّ عَلَى الفَلَاح، حَىَّ عَلَى الفَلَاح قَالَ: قَدْ قَامَتِ الصَّلَاةُ قَدْ قَامَتِ الصَّلَاة، اللَّه أكْبَر اللَّه أَكْبَر، لَا إلَهَ إِلَّا اللَّه، فَقَامَ عُمَر بن الخَطَّاب فَقَالَ: يَا رَسُولَ اللَّهِ! لَقَد طَافَ بى اللَّيْلَة مِثْلَ الَّذِى أَطَافَ بِهِ فَقَالَ: مَا مَنَعَكَ أَنْ تُخْبِرَنَا؟ قَالَ: سَبَقَنِى عَبْد اللَّه بن زَيْد فَاسْتَحَيْيتُ، فَأعْجَبَ ذَلِكَ المُسْلِمينَ، وَكَانَت سُنَّة بَعْدُ، وَأَمَر بِلالًا فَأَذَّنَ".
