حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سُلَيْمَانَ بْنِ الأَشْعَثِ ، ثنا أَحْمَدُ بْنُ صَالِحٍ ، ثنا عَبْدُ اللَّهِ بْنُ وَهْبٍ ، أَخْبَرَنِي يُونُسُ ، عَنِ ابْنِ شِهَابٍ ، عَنْ سَالِمٍ ، عَنْ أَبِيهِ ، قَالَ : " كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُسَبِّحُ عَلَى الرَّاحِلَةِ أَيْنَ تَتَوَجَّهُ ، وَيُوتِرُ عَلَيْهَا ، غَيْرَ أَنَّهُ كَانَ لا يُصَلِّي عَلَيْهَا الْفَرِيضَةَ " .
Salim narrates from his father (Sayyiduna Abdullah bin Umar, may Allah be pleased with them both): The Prophet Muhammad (peace and blessings be upon him) used to offer voluntary prayers on his mount, regardless of which direction it was facing. He would also perform Witr on it, but he would not perform obligatory prayers on his mount.
