Sunan an-Nasa'i, Volume 2, Book 20, Hadith 1790 (DarusSalam) ⓘ

It was narrated from Aishah that: When the Messenger of Allah did not pray at night because he was prevented from doing so by sleep- meaning, sleep overwhelmed him- or by pain, he would pray twelve rak'ahs during the day.

أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ قَتَادَةَ، عَنْ زُرَارَةَ، عَنْ سَعْدِ بْنِ هِشَامٍ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ إِذَا لَمْ يُصَلِّ مِنَ اللَّيْلِ مَنَعَهُ مِنْ ذَلِكَ نَوْمٌ أَوْ وَجَعٌ صَلَّى مِنَ النَّهَارِ ثِنْتَىْ عَشْرَةَ رَكْعَةً ‏.‏
