If I am given a gift should I give something similar back to the giver?
Question

                One of the customs among the people in my village is to give gifts and money on special occasions, and the recipient of the gifts is expected to respond in kind when other people have special occasions too.

What is the ruling if a special occasion arises and a person does not have anything; does he have to give them a gift?.
Praise be to Allah. It is mustahabb [preferable] for the one who is given a gift to respond by giving something similar or better, because the Prophet  (peace and 
    blessings of Allaah be upon him) said: “Whoever does you a favour, then respond in kind, and if you cannot find anything to give him, then make 
    du’aa’ for him (and keep doing so) until you think that you have done enough.” Narrated by Abu Dawood and al-Nasaa’i. But the people of the 
    village should not oblige a poor person to give them gifts like those that they gave to him, rather what is prescribed in sharee’ah is for the 
    Muslim to give a gift and not expect something back in return, rather he should hope for the reward from Allaah. Whoever is given something is not 
    obliged to give something back to the giver, but if he does give him something, that is preferable. 
And 
    Allaah is the Source of strength.
