It was the day of the conquest (of Mecca) that she went to the Messenger of Allah ﷺ and he was staying at a higher part (of that city). The Messenger of Allah ﷺ got up for his bath. Fatimah held a curtain around him (in order to provide him privacy). He then put on his garments and wrapped himself with that and then offered eight rak'ahs of the forenoon prayer.
أَنَّ أُمَّ هَانِئٍ بِنْتَ أَبِي طَالِبٍ حَدَّثَتْهُ أَنَّهُ لَمَّا كَانَ عَامُ الْفَتْحِ أَتَتْ رَسُولَ اللَّهِ ﷺ وَهُوَ بِأَعْلَى مَكَّةَ قَامَ رَسُولُ اللَّهِ ﷺ إِلَى غُسْلِهِ فَسَتَرَتْ عَلَيْهِ فَاطِمَةُ ثُمَّ أَخَذَ ثَوْبَهُ فَالْتَحَفَ بِهِ ثُمَّ صَلَّى ثَمَانَ رَكَعَاتٍ سُبْحَةَ الضُّحَى
