"Ali: 70We took the covenant of the Children of Israel and sent them messengers, every time, there came to them a messenger with what they themselves desired not - some (of these) they called impostors, and some they (go so far as to) slay. 71They thought there would be no trial (or punishment); so they became blind and deaf; yet Allah (in mercy) turned to them; yet again many of them became blind and deaf. But Allah sees well all that they do."
