Repentance (tawbah) from accepting bribes

A man used to accept bribes. Then Allah guided him to righteousness.
What shall he do with what he used to earn as bribes?
There can be two situations. Either the bribes he used to accept were
from thosethat had been wronged who had to offer bribe as a means of
obtaining what was their right, in which case the repentant should
return them their amounts or articles or whatever. For what he took
from them is considered as having been taken by force or through
deceit. Or, the bribe was taken from an unjust (zalim) man like
hehimself was before repenting. (That is, someone who achieved
orattained things via bribes which were not his right.) This amount is
not be returned to him. Instead the repentant should spend it in a
charitable way, such as on the poor and the destitute. Likewise, he
must repent the harm he caused to people by giving their right away to
others who had no right to them, but rather obtained them via the use
of bribes.
