The Prophet consulted the people as to how he could call them to the prayer. They suggested a horn, but he disliked that because of the Jews (because the Jews used a horn). Then they suggested a bell but he disliked that because of the Christians (because the Christians used a bell). Then that night the call to the prayer was shown in a dream to a man among the Ansar whose name was 'Abdullah bin Zaid, and to 'Umar bin Khattab. The Ansari man came to the Messenger of Allah at night, and the Messenger of Allah commanded Bilal to give the call to the prayer. (Da'if)Zuhri said: "Bilal added the phrase "As-salatu khairum minan-nawm (the prayer is better than sleep)" to the call for the morning prayer, and the Messenger of Allah approved of that." 'Umar said: "O Messenger of Allah, I saw the same as he did, but he beat me to it."
أَنَّ النَّبِيَّ ﷺ اسْتَشَارَ النَّاسَ لِمَا يُهِمُّهُمْ إِلَى الصَّلاَةِ فَذَكَرُوا الْبُوقَ فَكَرِهَهُ مِنْ أَجْلِ الْيَهُودِ ثُمَّ ذَكَرُوا النَّاقُوسَ فَكَرِهَهُ مِنْ أَجْلِ النَّصَارَى فَأُرِيَ النِّدَاءَ تِلْكَ اللَّيْلَةَ رَجُلٌ مِنَ الأَنْصَارِ يُقَالُ لَهُ عَبْدُ اللَّهِ بْنُ زَيْدٍ وَعُمَرُ بْنُ الْخَطَّابِ فَطَرَقَ الأَنْصَارِيُّ رَسُولَ اللَّهِ ﷺ لَيْلاً فَأَمَرَ رَسُولُ اللَّهِ ﷺ بِلاَلاً بِهِ فَأَذَّنَ قَالَ الزُّهْرِيُّ وَزَادَ بِلاَلٌ فِي نِدَاءِ صَلاَةِ الْغَدَاةِ الصَّلاَةُ خَيْرٌ مِنَ النَّوْمِ فَأَقَرَّهَا رَسُولُ اللَّهِ ﷺ قَالَ عُمَرُ يَا رَسُولَ اللَّهِ قَدْ رَأَيْتُ مِثْلَ الَّذِي رَأَى وَلَكِنَّهُ سَبَقَنِي
