It is sunna to give gifts. The Messenger of Allah (peace and blessings be upon him) said, “Exchange gifts (frequently), and you’ll grow to love one another.” [Bukhari]
It is also sunna to accept gifts. The Prophet (Allah bless him and give him peace) did not accept charity, but he did accept gifts and wouldn’t refuse them. [Bukhari]
Gifts are given as expressions of love, appreciation, maintenance of ties, and in reciprocation, and are accepted for the first three of the above meanings.
One wouldn’t reject gifts unless there is a negative meaning greater than the good of gift exchange–such as when the gift is a means to harm; or it is excessive; or imposes an undue burden on the giver or recipient.
The gift belongs to the one who receives it. It is their right to give it away. However, discretion, tact, and the feelings of the giver should be considered carefully (both with regards to whether and how the gift is given away).
And Allah alone gives success.
