Al-Ma'idah 5:71

Wahasiboo alla takoonafitnatun faAAamoo wasammoo thumma taba AllahuAAalayhim thumma AAamoo wasammoo katheerun minhum wallahubaseerun bima yaAAmaloon

And they thought there would be no [resulting] punishment, so they became blind and deaf. Then Allāh turned to them in forgiveness; then [again] many of them became blind and deaf. And Allāh is Seeing of what they do.

They thought that no harm would follow. Therefore, they became blind and deaf. Then, Allah accepted their repentance, but again they turned blind and deaf, many of them. Allah is watchful of what they do.
