Is zakat due on entrusted money after the passing of a year (hawl), and is the previous permission of its owner sufficient, or must he be informed again before it is disbursed?

Scholars have differed regarding the sufficiency of giving out zakat on behalf of another without their permission, even if the owner approves it. The more cautious approach is to inform the owner of the wealth before giving it out so that they can form the intention of giving it out. This is the more apparent view according to some scholars, because it is an act of worship that requires intention.
