حَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ الْمِصْرِيُّ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ نَوْفَلٍ، أَنَّهُ قَالَ سَأَلْتُ فَلَمْ أَجِدْ أَحَدًا يُخْبِرُنِي أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ سَبَّحَ فِي سَفَرٍ حَتَّى أَخْبَرَتْنِي أُمُّ هَانِئٍ بِنْتُ أَبِي طَالِبٍ أَنَّهُ قَدِمَ عَامَ الْفَتْحِ فَأَمَرَ بِسِتْرٍ فَسُتِرَ عَلَيْهِ فَاغْتَسَلَ ثُمَّ سَبَّحَ ثَمَانِيَ رَكَعَاتٍ .
English Translation
It was narrated that 'Abdullah bin Harith bin Nawfal said:"I asked whether the Messenger of Allah prayed voluntary prayer when traveling, but I could not find anyone to tell me until Umm Hani' bint Abu Talib told me that he had come during the year of the Conquest (of Makkah). He ordered that a screen be held up, and that was done, and he took a bath; then he prayed eight Rak'ah (units) of voluntary prayer
