The Women - 4:36 Serve Allah and associate with Him nothing and no one. Do good to parents, relatives, orphans, the poor, near neighbors, distant neighbors, companions, travelers, and those to whom your oaths/agreements are due. Allah does not love the arrogant and conceited.
Only Allah is worthy to be served:
