The ruling on giving zakah to one whom one thought was poor, but who turned out to be wealthy

The questioner:
And if he gave it to one whom he thought was not eligible, but it turned out he was eligible, or the reverse.

The Shaykh:
Or the reverse: he gave it to one whom he thought was eligible, but it turned out he was not eligible; it turned out he was wealthy. It does not suffice for him, because when two men came to the Prophet (peace and blessings be upon him) asking him for charity, he said, "If you wish," meaning when the two men came to him asking for charity, he looked at them (peace and blessings be upon him) and found them to be robust, meaning strong. He said, "If you wish, I will give you from the charity, but it is not permissible for a wealthy person or one of strong vigor." So if he gave it to one whom he thought was eligible, but it became clear that he was not eligible because he was strong and able to earn a living, this giving does not suffice, because he placed it in a place other than its proper use; he gave it to one who is able to earn a living.

The questioner:
If it turned out he was eligible, or the reverse, it does not suffice for him except if he thought he was wealthy.

The Shaykh:
And otherwise, in one case: if he gave it to one whom he thought was wealthy
