“Prayers at night and during the day are to be offered two by two.”  

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ صَلاَةُ اللَّيْلِ وَالنَّهَارِ مَثْنَى مَثْنَى  

It was narrated from Umm Hani’ bint Abu Talib that on the day of the Conquest (of Makkah) the Messenger of Allah ﷺ prayed voluntary Duha with eight Rak’ah, saying the Salam after each two Rak’ah.  

أَنَّ رَسُولَ اللَّهِ ﷺ يَوْمَ الْفَتْحِ صَلَّى سُبْحَةَ الضُّحَى ثَمَانِيَ رَكَعَاتٍ سَلَّمَ مِنْ كُلِّ رَكْعَتَيْنِ  

“After each two Rak’ah there should be the Taslim.”  

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ فِي كُلِّ رَكْعَتَيْنِ تَسْلِيمَةٌ  

“The Messenger of Allah ﷺ said: ‘The night prayers are (to be offered) two by two. Say the Tashah-hud after each two Rakʿah, and raise your hands in all humility like one who is poor and needy and say: ‘Allāhummaghfir lī (O Allah, forgive me).’ And whoever does not do that, it is imperfect.’”  

رَسُولُ اللَّهِ ﷺ صَلاَةُ اللَّيْلِ مَثْنَى مَثْنَى وَتَشَهَّدُ فِي كُلِّ رَكْعَتَيْنِ وَتَبَاءَسُ وَتَمَسْكَنُ وَتُقْنِعُ وَتَقُولُ اللَّهُمَّ اغْفِرْ لِي فَمَنْ لَمْ يَفْعَلْ ذَلِكَ فَهِيَ خِدَاجٌ
