Chapter on Gifts
A gift (hiba) is the gratuitous transfer of property made while one is still alive.
It is recommended, and it becomes binding through any statement or action that conveys the donor’s intent.
Its conditions are eight:

1. that it be given by someone who is legally competent to dispose of his wealth;
2. that he do so willingly, not in jest;
3. that the item given be something whose sale is valid;
4. that the recipient be legally capable of ownership;
5. that the recipient accept the gift—verbally or by any act that indicates acceptance—before both parties engage in something that, by common usage, breaks off the transaction;
6. that the gift be immediate, not suspended;
7. that it not be limited to a set term; however, if it is tied to the lifetime of either party, it is binding and the time-stipulation is disregarded;
8. that it be without consideration: if a specific counter-item is stipulated, it is a sale, and if the consideration is unknown, the transaction is invalid.

There is no harm in giving a present with the expectation that the recipient will return something greater.

It is disliked to refuse1 a gift, no matter how small; rather, the sunnah is to repay the giver or to pray for him. If one knows that the gift was offered2 merely out of embarrassment, then returning it3 becomes obligatory.
