Arabic (Original)
حَدَّثَنَا يَحْيَى عَنِ ابْنِ عَجْلَانَ حَدَّثَنِي نَافِعٌ عَنِ ابْنِ عُمَرَ أَنَّهُ كَانَ يُصَلِّي عَلَى رَاحِلَتِهِ وَيُوتِرُ عَلَيْهَا وَيَذْكُرُ ذَلِكَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ.
English Translation
Yahya narrated to us, from Ibn 'Ajlan: Nafi' told me, from Ibn 'Umar, that he used to pray on his mount and perform witr on it, and he attributed that to the Prophet, peace and blessings be upon him.
