Sadaqah from Haram Wealth

Assalamu alaykum wa rahmatullahi wa barakatuhu,

When people ask what they should do with their haram income, after having made tawbah most of the times, they are told to give it sadaqah (in charity) without the intention of receiving any reward for this. My question is about the underlined clause: Does Allah Ta’ala not accept the tawbah or getting rid of this haram money, if he intends to receive reward? Or is it said to simply make sure, that a person is fully aware that he won’t receive any reward for this?

In other words, what happens (or could happen) if a person gives his haram money in charity and at the same time falsely intends for reward?

Jazakallahu khairan

Wa’alaykum as Salām wa raḥmatullāhi wa barakātuhu,

Ḥarām wealth is intrinsically contaminated and holds no value in the eyes of a Muslim. Thus, evenwhen a person makes tawbā, although he becomes purified from the sin of accumulating the wealth, that money will still remain polluted. It is incumbent upon him to dispose of it and he has no choice.
It is highly inappropriate to first disobey Allāh Ta’ālā by accumulating the contaminated wealth,then hope that He should reward you for disposing of it.

Furthermore, with what face can a person give such polluted wealth ‘in the part of Allāh’?

Thus, giving the wealth in charity is just a means of distancing oneself from wealth which was disliked by Allāh Ta’ālā whilst it was in his possession. One should feel ashamed of hoping for reward when giving away this wealth.

However, looking at the vast mercy of Allāh Ta’ālā, it is highly likely that Allāh Ta’ālā will reward a person, even when cleansing himself from ḥarām wealth.
