(The people) stood up for prayer and the Messenger of Allah ﷺ was talking in whispers with a man, and he did not discontinue the conversation till his Companions dozed off; he then came and led the prayer.
أُقِيمَتِ الصَّلاَةُ وَالنَّبِيُّ ﷺ يُنَاجِي رَجُلاً فَلَمْ يَزَلْ يُنَاجِيهِ حَتَّى نَامَ أَصْحَابُهُ ثُمَّ جَاءَ فَصَلَّى بِهِمْ
The Iqama for the prayer was announced while a man was talking to Messenger of Allah ﷺ privately. He continued talking in that way till the Prophet's companions slept, and afterwards the Prophet ﷺ got up and offered the prayer with them.
أُقِيمَتِ الصَّلاَةُ وَرَجُلٌ يُنَاجِي رَسُولَ اللَّهِ ﷺ فَمَا زَالَ يُنَاجِيهِ حَتَّى نَامَ أَصْحَابُهُ ثُمَّ قَامَ فَصَلَّى
The Iqama for the prayer was announced while a man was talking to Messenger of Allah ﷺ privately. He continued talking in that way till the Prophet's companions slept, and afterwards the Prophet ﷺ got up and offered the prayer with them. (Using translation from Bukhārī 6292)
أُقِيمَتِ الصَّلَاةُ وَرَجُلٌ يُنَاجِي رَسُولَ اللهِ ﷺ فَمَا زَالَ يُنَاجِيهِ حَتَّى نَامَ أَصْحَابُهُ ثُمَّ قَامَ فَصَلَّى
