You have to seek reward with Allah. If some worry, distress or grief befalls you, remember that it is an expiation for sin. If you lose one of your children, remember that he will intercede for you before Allah. If some disability or sickness befalls you, remember that it brings its own reward from Allah , which is preserved with Him. Hunger,sicknessnd poverty all bring their own rewards from Allah. Nothing is ever lost with Him. He keeps it as a trust with Him until He gives it to the owner in the Hereafter.
"Prayer is guaranteed to bring tranquillity and chase. "
