It is prescribed for you to calculate your Zakah and distribute it by yourselves among the legal beneficiaries, because it is a form of `Ibadah (worship). This is more cautious in order to discharge your obligation concerning it. However, it is permissible to
give the sum of Zakah to a person who is trustworthy, with regard to his faith and honesty, to distribute it among the deserving recipients on your behalf. If the authorized person is not trustworthy, it is not permissible to give it to him. Hence, your practice of giving your Zakah to the chief of the tribe is impermissible.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
