Allah Does Not Bless Riba

Allah states that He destroys Riba, either by removing this money from those who eat it, or by depriving them of the blessing, and thus the benefit of their money. Because of their Riba, Allah will torment them in this life and punish them for it on the Day of Resurrection. Allah said,
(Say: "Not equal are Al-Khabith (evil things) and At-Tayyib (good things), even though the abundance of Al-Khabith may please you'') ﴿5:100

(And put the wicked (disbelievers and doers of evil deeds) one over another, heap them together and cast them into Hell) ﴿8:37﴾, and,
(And that which you give in gift (to others), in order that it may increase (your wealth by expecting to get a better one in return) from other people's property, has no increase with Allah) ﴿30:39
Ibn Jarir said that Allah's statement,
(Allah will destroy Riba) is similar to the statement reported of `Abdullah bin Mas`ud, "Riba will end up with less, even if it was substantial.'' Imam Ahmad recorded a similar statement in Al-Musnad.
