So they went on until, when they met a boy, he slew him. (Musa) said: Have you slain an innocent person otherwise than for manslaughter? Certainly you have done an evil thing.

When your sister went and said: Shall I direct you to one who will take charge of him? So We brought you back to your mother, that her eye might be cooled and she should not grieve and you killed a man, then We delivered you from the grief, and We tried you with (a severe) trying. Then you stayed for years among the people of Madyan; then you came hither as ordained, O Musa.
