Giving zakah to one who abandons prayer and has small children

The questioner:
He says: Honorable Shaykh, may Allah grant you success, is it permissible to give the zakah of one's wealth to a person who does not pray and has small children? Is it permissible to give him the zakah out of mercy for these small children?

The Shaykh:
He does not give it to himself because he does not pray; this person is a disbeliever, and he has no authority over him. A disbeliever has no authority over Muslims. However, another one of their relatives may give it to them to spend on them. Another one of their relatives may give it to them to spend on them if they are different. As for this disbeliever, he is to be avoided and not considered a guardian for them. Yes.

The questioner:
And is it obligatory, regarding the zakah when giving it, to inform [the recipient] that it is zakah?

The Shaykh:
If the one to whom it is paid does not accept zakah, then inform him of that and do not deceive him. But if he accepts zakah and you do not know that he refuses it, give it to him and do not inform him. Yes.
