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.”
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”
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."
