Is it permissible to build mosques and schools and perform acts of charity or to buy religious tapes and books and distribute them with usurious money or from the income of music tapes and barbershops?

Mosques and Islamic schools should not be built with money originating from usury, because it is unlawful and impure wealth. These projects should be financed with good and lawful money, for the Prophet, peace and blessings be upon him, said: "Indeed, Allah is pure and does not accept anything but what is pure." Thus, Allah only accepts pure and lawful expenditure that grows and multiplies with Him.
