The ruling on paying zakah for the printing of books of knowledge

Question:
He says: Honorable Shaykh, may Allah grant you success, we hear a lot in this time of fatwas issued by some students of knowledge stating that it is permissible to pay zakah for the printing of books of knowledge and then distributing them. Is this permissible?

Answer:
No, this is not permissible. Zakah has specific categories of recipients, eight in number: This is a restriction; it does not extend beyond these eight categories. However, those who say it is distributed for da'wah and books claim that it falls under the phrase of Allah the Exalted, "and in the cause of Allah." They say that da'wah is one of the types included in "the cause of Allah." The correct view is that it is not included, because what is meant by the phrase of Allah the Exalted, "and in the cause of Allah," is jihad in the cause of Allah, for the expeditions, weapons, and whatever jihad in the cause of Allah requires. The meaning is in jihad.
