Ibn Abi Laila said: Prayer passed through three stages. And out people narrated to us that Messenger of Allah صلی اللہ علیہ وسلم said; it is to my liking that the prayer of Muslims or believers should be united (i. e., in congregation), so much so that I intended to send people to the houses to announce the time of prayer; and I also resolved that I should order people to stand at (the tops of) the forts and announce the time of the prayer for Muslims; and they struck the bell or were about to strike the bell (to announce the time for prayer). Then came a person from among the Ansar who said: Messenger of Allah, when I returned from you, as I saw your anxiety. I saw (in sleep) a person with two green clothes on him; he stood on the mosque and called (people) to prayer. He then sat down for a short while and stood up and pronounced in a like manner, except that he added: “The time for prayer has come”. If the people did not call me (a liar), and according to the version of Ibn al-Muthanna, if you did not call me (a liar). I would say that I was awake; I was awake; I was not asleep. The Messenger of Allah صلی اللہ علیہ وسلم said: According to the version of Ibn al-Muthanna, Allah has shown you a good (dream). But the version of Amr does not have the words: Allah has shown you a good (dream). Then ask Bilal to pronounce the ADHAN (to call to the prayer). Umar (in the meantime) said: I also had a dream like the one he had. But as he informed earlier. I was ashamed (to inform). Our people have narrated to us: when a person came (to the mosque during the prayer in congregation), he would ask (about the RAKAHS of prayer), and he would be informed about the number of RAKAHS already performed. They would stand (in prayer) along with the Messenger of Allah صلی اللہ علیہ وسلم: some in standing position; others bowing; some sitting and some praying along with the Messenger of Allah صلی اللہ علیہ وسلم. Ibn al-Muthanna reported from Amr from Hussain bin Abi Laila, saying ; Until Muadh came. Shubah said ; I heard it from Hussain who said: I shall follow the position (in the prayer in which I find him (the prophet)). . . you should do in a similar way. Abu Dawud said: I then turned to the tradition reported by Amr bin Marzuq he said; then Ma’adh came and they (the people) hinted at him. Shubah said; I heard it from hussain who said: Muadh then said; I shall follow the position (in the prayer when I join it) in which I find him (the prophet). He then said: Muadh has prayer when I join it in which I find him (the prophet). He then said: Muadh has introduced for you a SUNNAH (a model behaviour), so you should do in a like manner. He said; our people have narrated to us; when the Messenger of Allah صلی اللہ علیہ وسلم came to Madina, he commanded them (the people) to keep fast for three days. Thereafter the Quranic verses with regard to the fasts during Ramadan were revealed. But they were people who were not accustomed to keep fast ; hence the keeping of the fasts was hard for them; so those who could not keep fast would feed an indigent; then the month”. The concession was granted to the patient and the traveler; all were commanded to keep fast.
