Arabic (Original)
حَدَّثَنَا إِسْمَاعِيلُ يَعْنِي ابْنَ عُلَيَّةَ أَخْبَرَنَا هِشَامٌ الدَّسْتُوَائِيُّ عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ عَنْ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ قَالَ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُصَلِّي عَلَى رَاحِلَتِهِ نَحْوَ الْمَشْرِقِ فَإِذَا أَرَادَ أَنْ يُصَلِّيَ الْمَكْتُوبَةَ نَزَلَ فَاسْتَقْبَلَ الْقِبْلَةَ.
English Translation
Isma'il, that is Ibn Ulayyah, told us, Hisham al-Dastuwa'i informed us, from Yahya ibn Abi Kathir, from Muhammad ibn Abd al-Rahman, from Jabir ibn Abdullah, who said: The Messenger of Allah, peace and blessings be upon him, used to pray on his mount facing the east; but when he wanted to pray the obligatory prayer, he would dismount and face the qiblah.
