Spending Zakah on buying books, printing them, or paying for postal charges
A:
It is not lawful
to spend Zakah on buying books, printing them, or paying for postal charges, because the categories of Zakah recipients have been clarified by Allah (Glorified be He) in His Glorious Book as follows:
As-Sadaqât (here it means Zakât) are only for the Fuqarâ’ (poor), and the Masâkin (needy) and those employed to collect (the funds), and to attract the hearts of those who have been inclined (towards Islâm)
and so on, to the end of the verse.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
