[Machine] Bilal used to give the call to prayer when the sun had dipped, meaning it had set. He would not start the prayer until the Prophet ﷺ came out. And when the Prophet came out, Bilal would establish the prayer at the time when he could see him.
كَانَ بِلَالٌ يُؤَذِّنُ إِذَا دَحَضَتْ يَعْنِي الشَّمْسُ فَلَا يُقِيمُ حَتَّى يَخْرُجَ النَّبِيُّ ﷺ فَإِذَا خَرَجَ أَقَامَ الصَّلَاةَ حِينَ يَرَاهُ
Bilal summoned to prayer as the sun declined but did not pronounce Iqama till the Messenger of Allah ﷺ came out and the Iqama was pronounced on seeing him.
كَانَ بِلاَلٌ يُؤَذِّنُ إِذَا دَحَضَتْ فَلاَ يُقِيمُ حَتَّى يَخْرُجَ النَّبِيُّ ﷺ فَإِذَا خَرَجَ أَقَامَ الصَّلاَةَ حِينَ يَرَاهُ
[Machine] Bilal used to perform the call to prayer when the sun set, but he would not establish the prayer until he saw the Prophet Muhammad ﷺ . Then, when he saw him, he would proceed to establish the prayer.
كَانَ بِلَالٌ يُؤَذِّنُ إِذَا دَحَضَتِ الشَّمْسُ ثُمَّ لَا يُقِيمُ حَتَّى يَرَى النَّبِيَّ ﷺ فَإِذَا رَآهُ أَقَامَ حِينَ يَرَاهُ
