حَدَّثَنَا مُحَمَّدٌ هُوَ ابْنُ سَلَامٍ قَالَ أَخْبَرَنَا عَبْدُ الْوَهَّابِ الثَّقَفِيُّ قَالَ حَدَّثَنَا خَالِدٌ عَنْ أَبِي قِلَابَةَ عَنْ أَنَسِ بْنِ مَالِکٍ قَالَ لَمَّا کَثُرَ النَّاسُ قَالَ ذَکَرُوا أَنْ يَعْلَمُوا وَقْتَ الصَّلَاةِ بِشَيْئٍ يَعْرِفُونَهُ فَذَکَرُوا أَنْ يُورُوا نَارًا أَوْ يَضْرِبُوا نَاقُوسًا فَأُمِرَ بِلَالٌ أَنْ يَشْفَعَ الْأَذَانَ وَأَنْ يُوتِرَ الْإِقَامَةَ
صحیح بخاری · Hadith 606
Narrated Anas bin Malik: When the number of Muslims increased they discussed the question as to how to know the time for the prayer by some familiar means. Some suggested that a fire be lit (at the time of the prayer) and others put forward the proposal to ring the bell. Bilal was ordered to pronounce the wording of Adhan twice and of the Iqama once only.
