Ibn ‘Umar said that when the Muslims came to Medina they gathered and sought to know the time of prayer, but no one summoned them. One day they discussed the matter, and one of them said, “Use something like the bell of the Christians." Another said, “Use a horn like that of the Jews." But when ‘Umar said, “I suggest that you send a man to announce the prayer," God’s Messenger said, “Get up, Bilal, and summon to prayer."
God's Messenger ordered me to call the adhan for the dawn prayer and I did so. Then Bilal wanted to utter the iqama, but God’s Messenger said to him, “The man of Suda' has called the adhan, and he who calls the adhan utters the iqama.”
When God’s Messenger ordered a bell to be made so that it might be struck to gather the people for prayer, a man carrying a bell in his hand appeared to me while I was asleep, and I said, “Servant of God, will you sell the bell ?” When he asked what I would do with it and I replied that we would use it to call people to prayer, he said, “Shall I not guide you to something better than that?" I replied, “Certainly”; so he told me to say, “God is most great ...” and similarly in the iqama. When I told God’s Messenger in the morning what I had seen he said, “It is a genuine vision, if God will; so get up along with Bilal, and when you have taught him what you have seen let him use it in making the call to prayer, for he has a stronger voice than you have. So I got up along with Bilal and began to teach it to him, and he used it in making the call to prayer. ‘Umar b, al-Khattab heard that when he was in his house, and he came out trailing his cloak and said, “Messenger of God, by Him who has sent you with the truth, I have seen the same kind of thing as has been revealed," to which God’s Messenger replied, “To God be the praise!”
Abu Dawud, Darimi and Ibn Majah transmitted it, but Ibn Majah did not mention the iqama. Tirmidhi said that this is a sahih, tradition, but that it did not make the story of the bell explicit.
Jabir stated that God’s Messenger said to Bilal, “When you call the adhan speak deliberately, when you utter the iqama speak quickly, and leave between your adhan and your iqama time for one who eats to finish his food and one who drinks to finish his drink, and one who needs to relieve himself to do so. And do not get up to pray* till you see me do so.”
* This sentence is addressed not only to Bilal, as the plural is used.
Tirmidhi transmitted it and said, “I know it only from the tradition of ‘Abd al-Mun‘im, and it is an unknown isnad”
