Are books that are authored, printed, and distributed for free or sold considered commercial offerings subject to Zakat, and is it permissible to take Zakat funds to pay off personal debts?

There is no zakat on books distributed for free, nor on books sold where the proceeds are used to print other books for the dissemination of knowledge or for charity. However, for books owned by a specific person and sold for their personal benefit, zakat is obligatory if their value reaches the nisab and a year has passed over them. The eligibility of the questioner to receive zakat depends on whether they are among the categories of zakat recipients mentioned in the Quran.
