7:127The chiefs of Pharaoh's people said, “Will you let Moses and his people cause trouble in the land, and forsake you and your gods?” He said, “We will kill their sons, and spare their women. We have absolute power over them.”

7:141Remember how We saved you from Pharaoh’s people, who subjected you to the worst of sufferings—killing your sons and sparing your women. In that was a tremendous trial from your Lord.

7:150And when Moses returned to his people, angry and disappointed, he said, “What an awful thing you did in my absence. Did you forsake the commandments of your Lord so hastily?” And he threw down the tablets; and he took hold of his brother’s head, dragging him towards himself. He said, “Son of my mother, the people have overpowered me, and were about to kill me; so do not allow the enemies to gloat over me, and do not count me among the unjust people.”

7:189It is He who created you from a single person, and made from it its mate, that he may find comfort with her. Then, when he has covered her, she conceives a light load, and she carries it around. But when she has grown heavy, they pray to God their Lord, “if You give us a good child, we will be among the thankful.”
