we did not send a messenger except that he should be obeyed by the permission of allah. if when they wronged themselves they had come to you and asked allah for forgiveness and the messenger had asked for forgiveness for them they would have found allah the turner the most merciful.
وما أرسلنا من رسول إلا ليطاع بإذن الله ولو أنهم إذ ظلموا أنفسهم جاءوك فاستغفروا الله واستغفر لهم الرسول لوجدوا الله توابا رحيما
