I have more than three hundred Islamic tapes; should I pay Zakah on them?

A: If these tapes are for sale and their content is free from anything that may contradict Allah's Purified Shar` (Law), they are considered commercial commodities on which Zakah is due, when their value reaches the Nisab (the minimum amount on which Zakah is due) and then a Hawl (one lunar year calculated from the time a property reaches the minimum amount upon which Zakah is due) passes. The due Zakah is 2.5 % of their value at the time when Zakah is due which is after the passage of one Hawl.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
