When the Muslims arrived at Medina, they used to assemble for the prayer, and used to guess the time for it. During those days, the practice of Adhan for the prayers had not been introduced yet. Once they discussed this problem regarding the call for prayer. Some people suggested the use of a bell like the Christians, others proposed a trumpet like the horn used by the Jews, but ʿUmar was the first to suggest that a man should call (the people) for the prayer; so Messenger of Allah ﷺ ordered Bilal to get up and pronounce the Adhan for prayers.  

بَعْضُهُمْ اتَّخِذُوا نَاقُوسًا مِثْلَ نَاقُوسِ النَّصَارَى وَقَالَ بَعْضُهُمْ بَلْ بُوقًا مِثْلَ قَرْنِ الْيَهُودِ فَقَالَ عُمَرُ أَوَلاَ تَبْعَثُونَ رَجُلاً يُنَادِي بِالصَّلاَةِ فَقَالَ رَسُولُ اللَّهِ ﷺ يَا بِلاَلُ قُمْ فَنَادِ بِالصَّلاَةِ  

When the Muslims came to Medina, they gathered and sought to know the time of prayer but no one summoned them. One day they discussed the matter, and some of them said: Use something like the bell of the Christians and some of them said: Use horn like that of the Jews. Umar said: Why may not a be appointed who should call (people) to prayer? The Messenger of Allah ﷺ said: O Bilal, get up and summon (the people) to prayer.  

أَنَّهُ قَالَ كَانَ الْمُسْلِمُونَ حِينَ قَدِمُوا الْمَدِينَةَ يَجْتَمِعُونَ فَيَتَحَيَّنُونَ الصَّلَوَاتِ وَلَيْسَ يُنَادِي بِهَا أَحَدٌ فَتَكَلَّمُوا يَوْمًا فِي ذَلِكَ فَقَالَ بَعْضُهُمُ اتَّخِذُوا نَاقُوسًا مِثْلَ نَاقُوسِ النَّصَارَى وَقَالَ بَعْضُهُمْ قَرْنًا مِثْلَ قَرْنِ الْيَهُودِ فَقَالَ عُمَرُ أَوَلاَ تَبْعَثُونَ رَجُلاً يُنَادِي بِالصَّلاَةِ قَالَ رَسُولُ اللَّهِ ﷺ يَا بِلاَلُ قُمْ فَنَادِ بِالصَّلاَةِ  

"When the Muslims arrived in Al-Madinah they used to gather and try to figure out the time for prayer, and no one gave the call to prayer. One day they spoke about that; some of them said: 'Let us use a bell like the Christians do;' others said, 'No, a horn like the Jews have.' 'Umar, may ,Allah be pleased with him, said: 'Why don't you send a man to announce the time of prayer?' The Messenger of Allah ﷺ said: 'O Bilal, get up and give the call to prayer.'"  

أَنَّهُ كَانَ يَقُولُ كَانَ الْمُسْلِمُونَ حِينَ قَدِمُوا الْمَدِينَةَ يَجْتَمِعُونَ فَيَتَحَيَّنُونَ الصَّلاَةَ وَلَيْسَ يُنَادِي بِهَا أَحَدٌ فَتَكَلَّمُوا يَوْمًا فِي ذَلِكَ فَقَالَ بَعْضُهُمُ اتَّخِذُوا نَاقُوسًا مِثْلَ نَاقُوسِ النَّصَارَى وَقَالَ بَعْضُهُمْ بَلْ قَرْنًا مِثْلَ قَرْنِ الْيَهُودِ فَقَالَ عُمَرُ ؓ أَوَلاَ تَبْعَثُونَ رَجُلاً يُنَادِي بِالصَّلاَةِ فَقَالَ رَسُولُ اللَّهِ ﷺ يَا بِلاَلُ قُمْ فَنَادِ بِالصَّلاَةِ  

"When the Muslims arrived in AI-Madinah, they used to assemble for the Salat, and guess the time for it there was no one who called for it (the prayer). One day they discussed that and some of them said that they should use a bell like the bell the Christians use. Others said they should use a trumpet like the horn the Jews use. But Umar [bin Al-Khattab] said: 'Wouldn't it better if we had a man call for the prayer?'" He said: "So Messenger of Allah said: 'O Bilal! Stand up and call for the Salat.'"  

كَانَ الْمُسْلِمُونَ حِينَ قَدِمُوا الْمَدِينَةَ يَجْتَمِعُونَ فَيَتَحَيَّنُونَ الصَّلَوَاتِ وَلَيْسَ يُنَادِي بِهَا أَحَدٌ فَتَكَلَّمُوا يَوْمًا فِي ذَلِكَ فَقَالَ بَعْضُهُمُ اتَّخِذُوا نَاقُوسًا مِثْلَ نَاقُوسِ النَّصَارَى وَقَالَ بَعْضُهُمُ اتَّخِذُوا قَرْنًا مِثْلَ قَرْنِ الْيَهُودِ قَالَ فَقَالَ عُمَرُ بْنُ الْخَطَّابِ أَوَلاَ تَبْعَثُونَ رَجُلاً يُنَادِي بِالصَّلاَةِ قَالَ فَقَالَ رَسُولُ اللَّهِ ﷺ يَا بِلاَلُ قُمْ فَنَادِ بِالصَّلاَةِ
