The ruling on giving zakah on behalf of another person without their permission

Question:
May Allah reward you. This is a questioner for the program al-Haqqiyyah who sent a set of questions written in clear handwriting and printed. He says: I usually give the zakah on my wealth, and on my wife’s gold and her wealth, as well as my father’s and mother’s, without informing them. Is this permissible, or is intention required in giving it, and therefore must they be informed?

Answer:
Yes, it is not permissible for a person to give zakah on behalf of another except with the permission of the owner of the zakah; because it is an act of worship that requires intention at the time of payment, so the permission of the one upon whom zakah is obligatory is required for the agent to pay it on his behalf. As for if another person gives it on his behalf without his permission and without his knowledge, it does not suffice; because it lacks the intention. And the Messenger (peace and blessings be upon him) said: And giving zakah is an act of worship and a deed. This is the vessel. Yes.
