The ruling on giving zakah without informing the recipient that it is zakah

The questioner : He paid the zakah of his wealth and then gave it to those who were entitled to it, but he did not inform them that it was zakah. Does this suffice for him?

The Shaykh : Yes, it suffices for him, provided that it is their custom to receive zakah.

The questioner : But if they are from the two categories [of those who do not receive zakah].

The Shaykh : The criterion is his intention. As long as they are from the people entitled to zakah, the criterion is his intention.
