Only Um Hani told us that she had seen the Prophet ﷺ offering the Duha (forenoon prayer). She said, "On the day of the conquest of Mecca, the Prophet ﷺ took a bath in my house and offered eight rakʿat. I never saw him praying such a light prayer but he performed perfect prostration and bowing. (Using translation from Bukhārī 1103)   

أَنَّهُ رَأَى رَسُولَ اللهِ ﷺ يُصَلِّي الضُّحَى غَيْرُ أُمِّ هَانِئٍ فَإِنَّهَا ذَكَرَتْ يَوْمُ فَتْحِ مَكَّةَ أَنَّهُ اغْتَسَلَ فِي بَيْتِهَا ثُمَّ صَلَّى ثَمَانِيَ رَكَعَاتٍ قَالَتْ «مَا رَأَيْتُهُ صَلَّى صَلَاةً أَخَفَّ مِنْهَا غَيْرَ أَنَّهُ كَانَ يَتِمُّ الرُّكُوعَ وَالسُّجُودَ»
