No amount of worrying can change the future. Go easy on yourself, for the outcome of all affairs is determined by God's decree. If something is meant to go elsewhere, it will never come your way, but if it is yours by destiny, from you it cannot flee...
No amount of guilt can change the past, and no amount of worrying can change the future.
We were the most humiliated people on earth and God gave us honour through Islam. If we ever seek honour through anything else, God will humiliate us again.
