The Lord of the worlds provides for the worm in the ground, Allah (GOD) provides for the birds in the sky and for the fish in the sea.
You are worthier than a worm, bird, or fish, so don’t worry about sustenance.
I have known people who were stricken by poverty simply because of their distance from Allah (GOD). Some of them were rich and healthy, but instead of being thankful they turned away from obedience to Allah (GOD), they abandoned prayer, and they perpetrated major sins. Allah (GOD) took away from them their health and their wealth, replacing these with poverty, sickness, and anxiety. They were then afflicted with hardship upon hardship, calamity upon calamity.
