Allah's Messenger (ﷺ) said, "When the Adhan is pronounced Satan takes to his heels and passes wind with noise during his flight in order not to hear the Adhan. When the Adhan is completed he comes back and again takes to his heels when the Iqama is pronounced and after its completion he returns again till he whispers into the heart of the person (to divert his attention from his prayer) and makes him remember things which he does not recall to his mind before the prayer and that causes him to forget how much he has prayed."

Anas said, "Bilal was ordered to pronounce the wording of Adhan twice and of Iqama once only." The sub narrator Isma`il said, "I mentioned that to Aiyub and he added (to that), "Except Iqama (i.e. Qadqamat- is-salat which should be said twice).

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.

Bilal was ordered to repeat the wording of the Adhan for prayers twice, and to pronounce the wording of the Iqama once except "Qad-qamat-is-salat".

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 `Umar was the first to suggest that a man should call (the people) for the prayer; so Allah's Messenger (ﷺ) ordered Bilal to get up and pronounce the Adhan for prayers.

The people mentioned the fire and the bell (they suggested those as signals to indicate the starting of prayers), and by that they mentioned the Jews and the Christians. Then Bilal was ordered to pronounce Adhan for the prayer by saying its wordings twice, and for the Iqama (the call for the actual standing for the prayers in rows) by saying its wordings once. (Iqama is pronounced when the people are ready for the prayer).

`Abdur Rahman bin Abi Bakr said, "The Suffa Companions were poor people and the Prophet (ﷺ) said, 'Whoever has food for two persons should take a third one from them (Suffa companions). And whosoever has food for four persons he should take one or two from them' Abu Bakr took three men and the Prophet (ﷺ) took ten of them." `Abdur Rahman added, my father my mother and I were there (in the house). (The sub-narrator is in doubt whether `Abdur Rahman also said, 'My wife and our servant who was common for both my house and Abu Bakr's house). Abu Bakr took his supper with the Prophet (ﷺ) and remained there till the `Isha' prayer was offered. Abu Bakr went back and stayed with the Prophet (ﷺ) till the Prophet (ﷺ) took his meal and then Abu Bakr returned to his house after a long portion of the night had passed. Abu Bakr's wife said, 'What detained you from your guests (or guest)?' He said, 'Have you not served them yet?' She said, 'They refused to eat until you come. The food was served for them but they refused." `Abdur Rahman added, "I went away and hid myself (being afraid of Abu Bakr) and in the meantime he (Abu Bakr) called me, 'O Ghunthar (a harsh word)!' and also called me bad names and abused me and then said (to his family), 'Eat. No welcome for you.' Then (the supper was served). Abu Bakr took an oath that he would not eat that food. The narrator added: By Allah, whenever any one of us (myself and the guests of Suffa companions) took anything from the food, it increased from underneath. We all ate to our fill and the food was more than it was before its serving. Abu Bakr looked at it (the food) and found it as it was before serving or even more than that. He addressed his wife (saying) 'O the sister of Bani Firas! What is this?' She said, 'O the pleasure of my eyes! The food is now three times more than it was before.' Abu Bakr ate from it, and said, 'That (oath) was from Satan' meaning his oath (not to eat). Then he again took a morsel (mouthful) from it and then took the rest of it to the Prophet. So that meal was with the Prophet. There was a treaty between us and some people, and when the period of that treaty had elapsed the Prophet (ﷺ) divided us into twelve (groups) (the Prophet's companions) each being headed by a man. Allah knows how many men were under the command of each (leader). So all of them (12 groups of men) ate of that meal."

The Prophet (ﷺ) prayed one of the `Isha' prayer in his last days and after finishing it with Taslim, he stood up and said, "Do you realize (the importance of) this night? Nobody present on the surface of the earth tonight would be living after the completion of one hundred years from this night." The people made a mistake in grasping the meaning of this statement of Allah's Messenger (ﷺ) and they indulged in those things which are said about these narrators (i.e. some said that the Day of Resurrection will be established after 100 years etc.) But the Prophet (ﷺ) said, "Nobody present on the surface of earth tonight would be living after the completion of 100 years from this night"; he meant "When that century (people of that century) would pass away."

Once he waited for Al-Hasan and he did not show up till it was about the usual time for him to start his speech; then he came and apologized saying, "Our neighbors invited us." Then he added, "Narrated Anas, 'Once we waited for the Prophet (ﷺ) till it was midnight or about midnight. He came and led the prayer, and after finishing it, he addressed us and said, 'All the people prayed and then slept and you had been in prayer as long as you were waiting for it." Al-Hasan said, "The people are regarded as performing good deeds as long as they are waiting for doing good deeds." Al-Hasan's statement is a portion of Anas's [??] Hadith from the Prophet (ﷺ) .

My father and I went to Abi Barza Al-Aslami and my father said to him, "Tell us how Allah's Messenger (ﷺ) used to offer the compulsory congregational prayers." He said, "He used to pray the Zuhr prayer, which you call the first prayer, as the sun declined at noon, the `Asr at a time when one of US could go to his family at the farthest place in Medina while the sun was still hot. (The narrator forgot what Abu Barza had said about the Maghrib prayer), and the Prophet (ﷺ) preferred to pray the `Isha' late and disliked to sleep before it or talk after it. And he used to return after finishing the morning prayer at such a time when it was possible for one to recognize the person sitting by his side and he (the Prophet) used to recite 60 to 100 'Ayat' (verses) of the Qur'an in it."
