Paying Zakah on behalf of some person without informing him

Q 1: I have a female relative who has some surplus money. She entrusted me with keeping this money and now a full Hawl (one lunar year calculated from the time a property reaches the minimum amount upon which Zakah is due) has passed. Should I pay the Zakah (obligatory charity) due on this money on her behalf or leave the matter totally to her, whether she pays it or not? Please, advise. May Allah reward you with the best!

A 1: It is impermissible for you to pay the Zakah due on her money, which is deposited with you, except after informing her and after she deputizes you to pay it because she may pay the Zakah while you are not aware. It is better to talk to her about the issue out of keenness to fulfill this Rukn (integral pillar) and cooperate in righteousness and Taqwa (fear/wariness of offending Allah).
