الشرح المختصر

"Isteethāq" (authentication) of transactions through one of the means of "isteethāq" is permissible, for people need it in their dealings to avoid the potential denial or loss of their rights and to retrieve information easily in cases of dispute or forgetfulness. Means of "isteethāq" include: writing down, issuing muniments, pawning, having witnesses, undertaking, suretyship, right of retention, etc. "Isteethāq" expires with the termination of its cause.
