Narrated Anas:

The Iqama for the prayer was announced while a man was talking to Allah's Messenger (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.

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ عَبْدِ الْعَزِيزِ، عَنْ أَنَس ٍ ـ رضى الله عنه ـ قَالَ أُقِيمَتِ الصَّلاَةُ وَرَجُلٌ يُنَاجِي رَسُولَ اللَّهِ صلى الله عليه وسلم فَمَا زَالَ يُنَاجِيهِ حَتَّى نَامَ أَصْحَابُهُ، ثُمَّ قَامَ فَصَلَّى‏.‏
