42:8Had God willed, He could have made them one community, but He admits into His mercy whomever He wills. As for the wrongdoers, they will have no protector and no savior.

42:24Or do they say, “He forged a lie about God.” If God so willed, He could have sealed your heart. But God obliterates the false, and confirm the true by His Words. He knows what is in the hearts.

42:33If He willed, He could have stilled the winds, leaving them motionless on its surface. Surely in that are signs for every disciplined, grateful person.

42:34Or He could wreck them, because of what they have earned. And yet He pardons much.
