Is it permissible to give Zakat to someone without telling them that this is the money of Zakat?

According to Shia scholarship, the matter of giving zakat without disclosing its nature is addressed in Al-Kafi. There is a narration where it is stated: I said to Abu Ja'far (peace be upon him): A man among us feels shy to take from the zakat. So I give him from the zakat without telling him it is from zakat. He said: Give it to him, do not tell him, and do not humiliate the believer. Al-Kafi 5:262ShiaSahih. This indicates that it is permissible to give zakat without informing the recipient that it is zakat, especially if it helps to maintain their dignity and comfort.

On the other hand, Sunni scholarship does not provide a definitive ruling on this specific question in the retrieved material. However, the general understanding is that the intention behind giving zakat should be to fulfill the obligation and aid those in need, regardless of whether the recipient is informed of the source.

For a ruling that applies to your specific situation, consult a qualified local scholar.
