Narrated Abu Huraira:
حَدَّثَنَا إِسْحَاقُ بْنُ نَصْرٍ ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ ، أَخْبَرَنَا مَعْمَرٌ ، عَنْ هَمَّامٍ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم عَرَضَ عَلَى قَوْمٍ الْيَمِينَ فَأَسْرَعُوا، فَأَمَرَ أَنْ يُسْهَمَ بَيْنَهُمْ فِي الْيَمِينِ أَيُّهُمْ يَحْلِفُ.
The Prophet (ﷺ) asked some people to take an oath, and they hurried for it. The Prophet (ﷺ) ordered that lots should be drawn amongst them as to who would take an oath first.
