Hadith 5826

(حديث مرفوع) حَدَّثَنَا عَبْدُ الْوَهَّابِ ، أَخْبَرَنَا هِشَامٌ ، عَنْ حَمَّادٍ , عَنْ عَبْدِ الرَّحْمَنِ بْنِ سَعْدٍ مَوْلَى عُمَرَ بْنِ الْخَطَّابِ , أَنَّهُ أَبْصَرَ عَبْدَ اللَّهِ بْنَ عُمَرَ : " يُصَلِّي عَلَى رَاحِلَتِهِ لِغَيْرِ الْقِبْلَةِ تَطَوُّعًا " ، فَقَالَ : مَا هَذَا يَا أَبَا عَبْدِ الرَّحْمَنِ ؟ قَالَ : كَانَ نَبِيُّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَفْعَلُهُ .
Abdur Rahman bin Sa’d (may Allah have mercy on him) says that he saw Sayyiduna Ibn Umar (may Allah be pleased with them both) performing voluntary prayers on his mount, regardless of which direction it was facing. He once asked him about this, so he replied that the Prophet (peace and blessings be upon him) used to do the same.
