Prayer at Night (Tahajjud)
19/32. Chapter:
Whoever did not offer the Duha prayer and thought it permissible (to offer it)
Sahih Bukhari
حَدَّثَنَا آدَمُ، قَالَ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ مَا رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم سَبَّحَ سُبْحَةَ الضُّحَى، وَإِنِّي لأُسَبِّحُهَا.
Narrated `Aisha: I never saw the Prophet (ﷺ) offering the Duha prayer but I always offer it.
