To offer the Salat-ud-Duha in journey
حَدَّثَنَا آدَمُ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا عَمْرُو بْنُ مُرَّةَ، قَالَ سَمِعْتُ عَبْدَ الرَّحْمَنِ بْنَ أَبِي لَيْلَى، يَقُولُ مَا حَدَّثَنَا أَحَدٌ، أَنَّهُ رَأَى النَّبِيَّ صلى الله عليه وسلم يُصَلِّي الضُّحَى غَيْرَ أُمِّ هَانِئٍ فَإِنَّهَا قَالَتْ إِنَّ النَّبِيَّ صلى الله عليه وسلم دَخَلَ بَيْتَهَا يَوْمَ فَتْحِ مَكَّةَ فَاغْتَسَلَ وَصَلَّى ثَمَانِيَ رَكَعَاتٍ فَلَمْ أَرَ صَلاَةً قَطُّ أَخَفَّ مِنْهَا، غَيْرَ أَنَّهُ يُتِمُّ الرُّكُوعَ وَالسُّجُودَ.

She said, "On the day of the conquest of Mecca, the Prophet (ﷺ) entered my house, took a bath and offered eight rak`at (of Duha prayers. I had never seen the Prophet (ﷺ) offering such a light prayer but he performed bowing and prostrations perfectly .
