In another Hadith, Rasulullah Sallallaahu Alaihi Wa Sallam explained that haraam wealth is so accursed that even if one gives it in charity, it will not be accepted and he will not receive any reward
Hazrat Abdullah bin Mas’ood reports that Rasulullah Sallallaahu Alaihi Wa Sallam said,
“If a servant of Allah Ta’laa earns any haraam wealth and gives it in charity, then it is not accepted from him. If he spends any of the haraam wealth then he is not granted barakah (blessings) in it, and if he leaves it behind after his demise then it becomes his provision to the hellfire. Indeed Allah does not forgive and erase an evil deed with that which is evil (ie. Allah will not accept haraam wealth that is given in charity, and hence the charity will not become a means of the person’s sins being forgiven). Rather, Allah Ta’ala forgives and erases evil with that which is good and pure. Indeed, that which is filth cannot purify and remove that which is filth, “شعب الإيمان للبيهقي
In another Hadith, Rasulullah Sallallaahu Alaihi WA Sallam further cautioned the Ummah regarding the consumption of haraam and mentioned that the one who consumes haraam will burn in Jahannum.
Rasulullah Sallallaahu Alaihi Wa Sallam said,
“The flesh (body) which is nourished with haraam will not enter jannah, and the fire of Jahannum is more deserving of every flesh (body) that is nourished with haraam.” المعجم الكبير للطبراني
From the above Ahaadith, it is clear that prosperity, happiness and barakah will only be acquired and enjoyed if one’s earnings are halaal. On the contrary, earning and consuming haraam is a source of nothing but misery and misfortune in this world and the next.
