Is it permissible for a Muslim woman to acquire usurious wealth from the estate of a disbelieving woman?

A will from a disbeliever to a Muslim is valid, but the usurious increase does not belong to the usurer; rather, only the principal sum belongs to him. So, if the usurer bequeaths the usurious increase to someone, the will is invalid because he does not own it. However, if the usurer disposes of the increase during his lifetime by giving it to a poor person or a needy one, he has done well. If the usurer dies, the usurious profits are given to the poor and needy and spent on public interests, and the heirs do not inherit them.
