It was narrated that Usmah bin Zaid said:

"I was a companion rider with the Prophet at Arafat. He raised his hands in supplication, so his she-camel began leaning and he dropped he halter, so he tool the halter while one of his hand while he was raising the other hand."

أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، عَنْ هُشَيْمٍ، قَالَ حَدَّثَنَا عَبْدُ الْمَلِكِ، عَنْ عَطَاءٍ، قَالَ قَالَ أُسَامَةُ بْنُ زَيْدٍ كُنْتُ رَدِيفَ النَّبِيِّ ﷺ بِعَرَفَاتٍ فَرَفَعَ يَدَيْهِ يَدْعُو فَمَالَتْ بِهِ نَاقَتُهُ فَسَقَطَ خِطَامُهَا فَتَنَاوَلَ الْخِطَامَ بِإِحْدَى يَدَيْهِ وَهُوَ رَافِعٌ يَدَهُ الأُخْرَى .
