The Prophet (saws) said: The angels do not go with a travelling company in which there is a bell.

The people mentioned the fire and the bell (as means proposed for announcing the time of prayer) and by such a suggestion they referred to the Jews and the Christians. But Bilal was ordered, "Pronounce the words of the Adhan (i.e. call for the prayer) twice and the Iqama once only."

That the Messenger of Allah (saws) said: "The angels do no accompany a group among whom there is a dog or a bell."

[Abu 'Eisa said:] There are narrations on this topic from Ibn 'Umar, Umm Habibah, and Umm Salamah. This Hadith is Hasan Sahih.

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.

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).

Al Harith bin Hisham asked the Prophet, "How does the divine inspiration come to you?" He replied, "In all these ways: The Angel sometimes comes to me with a voice which resembles the sound of a ringing bell, and when this state abandons me, I remember what the Angel has said, and this type of Divine Inspiration is the hardest on me; and sometimes the Angel comes to me in the shape of a man and talks to me, and I understand and remember what he says."

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 Apostle ordered Bilal to get up and pronounce the Adhan for prayers.

(the mother of the faithful believers) Al-Harith bin Hisham asked Allah's Apostle "O Allah's Apostle! How is the Divine Inspiration revealed to you?" Allah's Apostle replied, "Sometimes it is (revealed) like the ringing of a bell, this form of Inspiration is the hardest of all and then this state passes off after I have grasped what is inspired. Sometimes the Angel comes in the form of a man and talks to me and I grasp whatever he says." 'Aisha added: Verily I saw the Prophet being inspired divinely on a very cold day and noticed the sweat dropping from his forehead (as the Inspiration was over).

Yahya related to me from Malik from Hisham ibn Urwa from his father from A'isha, the wife of the Prophet, may Allah bless him and grant him peace, that al-Harith ibn Hisham asked the Messenger of Allah, may Allah bless him and grant him peace, "How does the revelation come to you?" and the Messenger of Allah, may Allah bless him and grant him peace, said, "Sometimes it comes to me like the ringing of a bell, and that is the hardest for me, and when it leaves me I remember what it has said. And sometimes the angel appears to me in the likeness of a man and talks to me and I remember what he says."

A'isha added, "I saw it coming down on him on an intensely cold day, and when it had left him his forehead was dripping with sweat."

AbuUmayr reported on the authority of his uncle who was from the Ansar (the helpers of the Prophet): The Prophet (saws) was anxious as to how to gather the people for prayer.

The people told him: Hoist a flag at the time of prayer; when they see it, they will inform one another. But he (the Prophet) did not like it. Then someone mentioned to him the horn.

Ziyad said: A horn of the Jews. He (the Prophet) did not like it. He said: This is the matter of the Jews. Then they mentioned to him the bell of the Christians. He said: This is the matter of the Christians. Abdullah ibn Zayd returned anxiously from there because of the anxiety of the Apostle (saws). He was then taught the call to prayer in his dream. Next day he came to the Messenger of Allah (saws) and informed him about it.

He said: Messenger of Allah, I was between sleep and wakefulness; all of a sudden a newcomer came (to me) and taught me the call to prayer. Umar ibn al-Khattab had also seen it in his dream before, but he kept it hidden for twenty days.

The Prophet (saws) said to me (Umar): What did prevent you from saying it to me?

He said: Abdullah ibn Zayd had already told you about it before me: hence I was ashamed.

Then the Messenger of Allah (saws) said: Bilal, stand up, see what Abdullah ibn Zayd tells you (to do), then do it. Bilal then called them to prayer.

AbuBishr reported on the authority of AbuUmayr: The Ansar thought that if Abdullah ibn Zayd had not been ill on that day, the Messenger of Allah (saws) would have made him mu'adhdhin.

Ibn al-Muthanna reported from ‘Amr from Hussain b. Abi Laila, saying ; Until Mu’adh came. Shu’bah 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 b. Marzuq he said; then Ma’adh came and they (the people) hinted at him. Shu’bah said; I heard it from hussain who said: Mu’adh then said; I shall follow the position (in the prayer when I join it) in which I find him (the prophet). He then said: Mu’adh has prayer when I join it in which I find him (the prophet). He then said: MU’adh 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 (may peace be upon him) 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.
