Hadith
حَدَّثَنَا جَمِيلُ بْنُ الْحَسَنِ الْعَتَكِيُّ، حَدَّثَنَا عَبْدُ الأَعْلَى، حَدَّثَنَا سَعِيدٌ، عَنْ قَتَادَةَ، عَنْ خِلاَسٍ، عَنْ أَبِي رَافِعٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَجُلَيْنِ، تَدَارَءَا فِي بَيْعٍ لَيْسَ لِوَاحِدٍ مِنْهُمَا بَيِّنَةٌ فَأَمَرَهُمَا رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ يَسْتَهِمَا عَلَى الْيَمِينِ أَحَبَّا ذَلِكَ أَمْ كَرِهَا .
It was narrated from Abu Hurairah that :two men disputed concerning a transaction, and neither of them had proof. The Messenger of Allah commanded them to draw lots as to which of them should swear an oath, whether they liked it or not
