With economic hardships, sourcing capital for businesses is becoming difficult and not straightforward. Few months ago, my friend earned money through gambling. He wants to invest the money into business. He got advice that after a certain period of time, the money becomes Halaal. Is the advice correct?

Question

Common sense is adequate for this. How can money obtained in this manner become permissible or Halaal? His income is contaminated with the filth of the Haraam money which constitutes the basis of his business. Gambling which is Haraam remains Haraam in all circumstances. The advice he got is wrong. It is therefore compulsory that he gives the Haraam amount as Sadaqah to the poor.
