Whether you can "donate" haram money depends on your intention and expected outcome. Giving away haram money does not earn you reward, but may be permissible as a means of repentance.
According to the reference, if you earn haram money through illicit means, you sin by doing so. Giving that money away will not result in a reward.
However, the reference also indicates that if you give away the haram money because you want to rid yourself of it and repent for earning it in the first place, you may receive reward for your good intentions. Essentially, the act of giving it away is not the charitable act that earns reward; rather, the intention to purify yourself from the illicit gain is what is potentially rewarded.
In summary:
| Aspect | Description | Reward? |
|---|---|---|
| Earning Haram Money | Committing a sin through illicit means. | No |
| Giving it Away | Giving away the ill-gotten money without the intention of repentance. | No |
| Repentance | Giving away the haram money as a form of repentance and to cleanse oneself of the illicit earning. | Yes (for the intention) |
It is important to note that this should be considered a way to dispose of ill-gotten wealth and purify oneself, rather than a charitable donation in the traditional sense.
