Ziyad b. al-Harith as-Suda’i said: 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 .” Tirmidhi, Abu Dawud and Ibn Majah transmitted it.
