Is it permissible to give a married son a portion of the father's zakat, with the intention of sharing the reward and the zakat in this amount?

Zakat on barley is to be given from the barley itself. It is not permissible to give money in lieu of it, according to the majority of scholars. Similarly, it is not permissible for a father to give zakat from his wealth to his poor or needy son, because his son's maintenance is obligatory upon him, unless he is unable to provide for his maintenance. It is not permissible to pay zakat in installments. It is permissible to distribute the zakat amount among several people, even if each person's share is small.
