Salam 3alykom wa rahmat Allah. I know that God has assigned certain people to be in others' service and help. I cannot hear of a person in need or help and not offer it, specialy my parents, my in-laws among my sisters and brothers .. But instead of leaving this for my ability and time. I am continually asked to do even if others can and should. My children are accusing me of being so weak and letting myself be used. I say it is God's will and it is His satisfaction that he made me servant to all. In fact, I am getting tired and wonder who is right my children or myself??
