Narrated Ibn Abu Laila:

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 took a bath in my house and offered eight Rakat. I never saw him praying such a light prayer but he performed perfect prostration and bowing. Narrated 'Abdullah bin amir that his father had told him that he had seen the Prophet ﷺ praying Nawafil at night on the back of his Mount on a journey, facing whatever direction it took.

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ عَمْرٍو، عَنِ ابْنِ أَبِي لَيْلَى، قَالَ مَا أَنْبَأَ أَحَدٌ، أَنَّهُ رَأَى النَّبِيَّ ﷺ صَلَّى الضُّحَى غَيْرُ أُمِّ هَانِئٍ ذَكَرَتْ أَنَّ النَّبِيَّ ﷺ يَوْمَ فَتْحِ مَكَّةَ اغْتَسَلَ فِي بَيْتِهَا، فَصَلَّى ثَمَانِ رَكَعَاتٍ، فَمَا رَأَيْتُهُ صَلَّى صَلاَةً أَخَفَّ مِنْهَا، غَيْرَ أَنَّهُ يُتِمُّ الرُّكُوعَ وَالسُّجُودَ.
