that when the Messenger of Allah ﷺ missed the night prayer due to pain or any other reason, he observed twelve rakahs during the daytime.

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا فَاتَتْهُ الصَّلاَةُ مِنَ اللَّيْلِ مِنْ وَجَعٍ أَوْ غَيْرِهِ صَلَّى مِنَ النَّهَارِ ثِنْتَىْ عَشْرَةَ رَكْعَةً.

from the Messenger of Allah ﷺ who said, "Allah ﷻ stretches out His Hand during the night to accept the repentance of the sinners of the day, and stretches out His Hand during the day to accept the repentance of the sinners of the night. ˹This will continue˺ until the sun rises from the west."

عَنِ النَّبِيِّ ﷺ قَالَ: «إِنَّ اللَّهَ ﷻ يَبْسُطُ يَدَهُ بِاللَّيْلِ لِيَتُوبَ مُسِيءُ النَّهَارِ، وَيَبْسُطُ يَدَهُ بِالنَّهَارِ لِيَتُوبَ مُسِيءُ اللَّيْلِ, حَتَّى تَطْلُعَ الشَّمْسُ مِنْ مَغْرِبِهَا».

[AI] "From the Messenger of Allah ﷺ , he said: Our Lord, the Blessed and Exalted, descends every night when the last third of the night remains, to the lowest heaven and says, 'Who is calling upon Me, so that I may answer him? Who is seeking My forgiveness, so that I may forgive him? Who is asking of Me, so that I may give him?'"

عَنْ رَسُولِ اللهِ ﷺ قَالَ ينْزِلُ رَبُّنَا تَبَارَكَ وَتَعَالَى كُلَّ لَيْلَةٍ حِينَ يَبْقَى ثُلُثُ اللَّيْلِ الْآخِرُ إِلَى السَّمَاءِ الدُّنْيَا فَيَقُولُ مَنْ يَدْعُونِي فَأَسْتَجِيبَ لَهُ؟ مَنْ يَسْتَغْفِرُنِي فَأَغْفِرَ لَهُ؟ مَنْ يَسْأَلُنِي فَأُعْطِيَهُ؟

[AI] “In Rajab there is a day and a night: whoever fasts that day and stands in prayer that night will be like one who has fasted for a hundred years and stood in prayer for a hundred years. It is when three days remain of Rajab, and in it Allah, the Exalted, sent Muhammad.”

"فِي رَجَب يَوْمٌ وَلَيلَةٌ، مَنْ صَامَ ذَلِكَ الْيَوْمَ، وَقَامَ تِلْكَ اللَّيلَةَ كانَ كمَنْ صَامَ مِن الدَّهْرِ مائَةَ سَنَةٍ، وَقَامَ مائَةَ سَنَةٍ، وَهُوَ لثَلاثٍ بَقينَ من رَجَبٍ وَفيه بَعَثَ اللهُ تَعَالى مُحَمَّدًا".
