حَدَّثَنَا إِسْمَاعِيلُ بْنُ عُمَرَ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ عَنْ شُعْبَةَ عَنِ ابْنِ عَبَّاسٍ أَنَّ أُسَامَةَ بْنَ زَيْدٍ كَانَ رِدْفَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَوْمَ عَرَفَةَ فَدَخَلَ الشِّعْبَ فَنَزَلَ فَأَهْرَاقَ الْمَاءَ ثُمَّ تَوَضَّأَ وَرَكِبَ وَلَمْ يُصَلِّ
مسند امام احمد بن حنبل · Hadith 2265
It was narrated from Ibn 'Abbas (RA) that Usamah bin Zaid was riding behind the Messenger of Allah (PBUH) on the day of 'Arafah. He went into a mountain pass and passed water, then he did wudoo and got back on his mount, but he did not pray.
