قَالَ رَسُولُ اللَّهِ ص الْبَيِّنَةُ عَلَى مَنِ ادَّعَى وَ الْيَمِينُ عَلَى مَنِ ادُّعِيَ عَلَيْهِ.
“Abu ‘ Abd Allah (a.s.), has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, ’Establishing testimony (the burden of proof) is on the plaintiff and oath is on the defendant.”’
