Moses (peace be upon him) asked Allah Almighty. O Allah when you are kind to your servant. So what do you grant. Allah Almighty said:
If married, daughter, Moses said again. Or if Allah is more merciful. Allah Almighty said again. So I give another daughter too. Moses said again. Or Allah, if you are the most merciful of all. So Allah Almighty said again. O Moses, I give you a third daughter. Allaah says (interpretation of the meaning): When I give a son to my servant. So go speak to this son and be your father's arm. And when the daughter grants. So I swear by my God that I will be his father's arm myself.
Daughter is a mercy of Allah. Will anyone share my daughter in the group?
