عَن ابْن عمر قَالَ: كَانَ الْأَذَانُ عَلَى عَهْدِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَرَّتَيْنِ مَرَّتَيْنِ وَالْإِقَامَةُ مَرَّةً مَرَّةً غَيْرَ أَنَّهُ كَانَ يَقُولُ: قَدْ قَامَتِ الصَّلَاةُ قَدْ قَامَتِ الصَّلَاةُ. رَوَاهُ أَبُو دَاوُد وَالنَّسَائِيّ والدارمي

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.
