My question is that can I donate the amount of interest in madrasa and if I had already done it what should be done now.
Answer
(Fatwa: 990/990/M=1433)
If there are poor and needy students in the madrasa then the interest money may be given to them but it is better not to give such malevolent money to the students of Islamic madrasa.
