Bequeathing the purchase of books containing innovations or endowing them

Question:
Your Eminence the Shaykh, what is the ruling on one who bequeaths the purchase of books or endows something that contains innovations? Is such a bequest executed?

Answer:
No, a bequest is only to be made for what is good, for beneficial and useful books. As for a bequest for books that contain evil, shirk (associating partners with Allah), and bid'ah (religious innovations), such a bequest is not valid because it is aggression and sin. However, it is possible, just as if one were to bequeath for a grave or for [something], that this bequest be directed toward permissible matters or matters of obedience, thereby changing its nature from being for evil to being for good. Yes. Yes? According to his intention, according to his intention. But the wealth is not lost; this is spent on good, because it is like lost wealth, which is spent on matters that benefit the Muslims. Yes.
