when the Messenger of Allah ﷺ ordered a bell to be made so that it might be struck to gather the people for prayer, a man carrying a bell in his hand appeared to me while I was asleep, and I said; servant of ‘abd Allah, will you sell the bell? He asked; what will you do with it? I replied; we shall use it to call the people to prayer. He said; should I not suggest you something better than that. I replied: certainly. Then he told me to say: Allah is most great, Allah is most great, Allah is most great, Allah is most great. I testify that there is no god but Allah, I testify that Muhammad is the Messenger of Allah. Come to pray, come to pray; come to salvation; come to salvation. Allah is most great, Allah is most great. I testify that there is no god but Allah. He then moved backward a few steps and said: when you utter the IQAMAH, you should say: Allah is most great, Allah is most great. I testify that there is no god but Allah, I testify that Muhammad is the Messenger of Allah. Come to prayer, come to salvation. The time for prayer has come, the time for prayer has come: Allah is most great, Allah is most great. There is no god but Allah. When the morning came, I came to the Messenger of Allah (May peace be upon him) and informed him of what I had seen in the dream. He said: it is a genuine vision, and he then should use it to call people to prayer, for he has a louder voice than you have. So I got up along with Bilal and began to teach it to him and he used it in making the call to prayer. ‘Umar b. al-khattab (Allah be pleased with him) heard it while he was in his house and came out trailing his cloak and said: Messenger of Allah. By him who has sent you with the truth, I have also seen the kind of thing as has been shown to him. The Messenger of Allah (May peace be upon him) said: To Allah be the praise. Abu Dawud said; Al-Zuhri narrated this tradition in a similar way from Sa’id b. al-Musayyib on the authority of ‘Abd Allah b. Zaid. In this version Ibn Ishaq narrated from al-Zuhri: Allah is most great. Allah is most great, Allah is most great, Allah is most great. Ma;mar and yunus narrated from al-Zuhri; Allah is most great, Allah is most great. They did not report it twice again. (Using translation from Abū Dāʾūd 499)   

وَقَدْ كَانَ رَسُولُ اللَّهِ ﷺ حِينَ قَدِمَهَا قَالَ أَبُو مُحَمَّدٍ يَعْنِي الْمَدِينَةَ إِنَّمَا يُجْتَمَعُ إِلَيْهِ بِالصَّلَاةِ لِحِينِ مَوَاقِيتِهَا بِغَيْرِ دَعْوَةٍ فَهَمَّ رَسُولُ اللَّهِ ﷺ أَنْ يَجْعَلَ بُوقًا كَبُوقِ الْيَهُودِ الَّذِينَ يَدْعُونَ بِهِ لِصَلَاتِهِمْ ثُمَّ كَرِهَهُ ثُمَّ أَمَرَ بِالنَّاقُوسِ فَنُحِتَ لِيُضْرَبَ بِهِ لِلْمُسْلِمِينَ إِلَى الصَّلَاةِ فَبَيْنَمَا هُمْ عَلَى ذَلِكَ إِذْ رَأَى عَبْدُ اللَّهِ بْنُ زَيْدِ بْنِ عَبْدِ رَبِّهِ أَخُو اَلْحَارِثِ بْنِ الْخَزْرَجِ فَأَتَى رَسُولَ اللَّهِ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّهُ طَافَ بِيَ اللَّيْلَةَ طَائِفٌ مَرَّ بِي رَجُلٌ عَلَيْهِ ثَوْبَانِ أَخْضَرَانِ يَحْمِلُ نَاقُوسًا فِي يَدِهِ فَقُلْتُ يَا عَبْدَ اللَّهِ أَتَبِيعُ هَذَا النَّاقُوسَ؟ فَقَالَ وَمَا تَصْنَعُ بِهِ؟ قُلْتُ نَدْعُو بِهِ إِلَى الصَّلَاةِ قَالَ أَفَلَا أَدُلُّكَ عَلَى خَيْرٍ مِنْ ذَلِكَ؟ قُلْتُ وَمَا هُوَ؟ قَالَ تَقُولُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ حَيَّ عَلَى الصَّلَاةِ حَيَّ عَلَى الصَّلَاةِ حَيَّ عَلَى الْفَلَاحِ حَيَّ عَلَى الْفَلَاحِ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ لَا إِلَهَ إِلَّا اللَّهُ ثُمَّ اسْتَأْخَرَ غَيْرَ كَثِيرٍ ثُمَّ قَالَ مِثْلَ مَا قَالَ وَجَعَلَهَا وِتْرًا إِلَّا أَنَّهُ قَالَ قَدْ قَامَتِ الصَّلَاةُ قَدْ قَامَتِ الصَّلَاةُ اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ لَا إِلَهَ إِلَّا اللَّهُ فَلَمَّا أخُبِّرَ بِهَا رَسُولُ اللَّهِ ﷺ قَالَ «إِنَّهَا لَرُؤْيَا حَقٌّ إِنْ شَاءَ اللَّهُ فَقُمْ مَعَ بِلَالٍ فَأَلْقِهَا عَلَيْهِ فَإِنَّهُ أَنْدَى صَوْتًا مِنْكَ» فَلَمَّا أَذَّنَ بِلَالٌ سَمِعَهَا عُمَرُ بْنُ الْخَطَّابِ وَهُوَ فِي بَيْتِهِ فَخَرَجَ إِلَى رَسُولِ اللَّهِ ﷺ وَهُوَ يَجُرُّ إِزَارَهُ وَهُوَ يَقُولُ يَا نَبِيَّ اللَّهِ وَالَّذِي بَعَثَكَ بِالْحَقِّ لَقَدْ رَأَيْتُ مِثْلَ مَا رَأَى فَقَالَ رَسُولُ اللَّهِ ﷺ «فَلِلَّهِ الْحَمْدُ فَذَاكَ أَثْبَتُ»

عَنْ أَبِيهِ بِهَذَا الحديثِ  

[Machine] When the Messenger of Allah commanded the use of bells, he mentioned something similar.  

لَمَّا أَمَرَ رَسُولُ اللَّهِ ﷺ بِالنَّاقُوسِ فَذَكَرَ نَحْوَهُ
