[Machine] The caller of prayer of the Messenger of Allah ﷺ would give the call to prayer and then wait. He would not establish the prayer until he saw the Prophet ﷺ had come out, then he would establish the prayer when he saw him.
«كَانَ مُؤَذِّنُ رَسُولِ اللهِ ﷺ يُؤَذِّنُ ثُمَّ يُمْهِلُ فَلَا يُقِيمُ حَتَّى إِذَا رَأَى النَّبِيَّ ﷺ قَدْ خَرَجَ أَقَامَ الصَّلَاةَ حِينَ يَرَاهُ»
