If you complain that Allah is testing you too much, you're failing the test.
Sometimes Allah gives you bitterness in this life so that you can further enjoy the sweetness of the hereafter.
Renew your intention EVERY day, EVERY time you pray, and EVERY time you are about to do a good deed or else shaytan will lead your heart and mind astray.
Kind words cost you nothing but are sometimes worth more than a million dollars.
Your success does not depend on the failure of others.
Love the people you think you'd want to be with in the hereafter.
