Is one who possesses ill-gotten wealth, but does not use it, deprived of having his supplications answered, despite his intention to give it away in the future?

Islam has forbidden illicit earnings because they bring misfortune and tribulation upon their owner, and they can be a cause for Allah's wrath and entry into Hell, as the Prophet (peace and blessings be upon him) said: "Whoever usurps the right of a Muslim by his oath, Allah will make Hellfire incumbent upon him and forbid Paradise for him." Similarly, a false oath is "a means of selling goods but destroys the blessing of earnings."

The texts indicate that being involved with haram in terms of food, drink, and clothing prevents the supplication from being answered, as the Prophet (peace and blessings be upon him) said: "Indeed, Allah is good and accepts only what is good... Then he mentioned a man who undertakes a long journey, dishevelled and dusty, extending his hands to the sky: 'O Lord! O Lord!' while his food is unlawful, his drink is unlawful, his clothing is unlawful, and he has been nourished with unlawful things, so how can he be answered?" This rhetorical question indicates the improbability of the supplication being answered, not its impossibility, as Allah might respond out of Hisفضل (grace).

Whoever possesses unlawful wealth must hasten to repent and dispose of it. If the money belongs to specific individuals, he should return it to them and ask for their forgiveness. If the owner is unknown, he should spend it on charitable causes and for the general welfare of Muslims. If he does so, the presence of such wealth will not prevent his supplication from being answered.
