When death approaches you , let two men of equity among you act as witnesses when you make your bequest ; or let two of those from others than yourselves act as witnesses if you are on a journey when the affliction of death befalls you . Then if any doubt occurs you shall detain both of them ( in the mosque ) after the Prayer , and they shall swear by Allah : ' We shall neither sell our testimony in return for any gain even though it concerns any near of kin nor shall we conceal our testimony which we owe to Allah , for then we should become among sinners . ' .
