English translation
606. Narrated Anas bin Mālik رضي الله عنه: When the number of Muslims increased they discussed the question as to how to know the time for Aṣ-Ṣalāt (the prayers) by some familiar means. Some suggested that a fire be lit [at the time of Ṣalāt (prayer)] and others put forward the proposal to ring the bell. Bilāl was ordered to pronounce the wording of Adhān twice (in doubles) and of the Iqāma once (in singles) only.
