The Supplication that Brings sustenance
Question :
What is the supplication that brings sustenance and blessings with it?
Answer:
I am not aware of a specific supplication that causes sustenance to come; yet fearing Allah Almighty is from the most potent means of causing sustenance to come. Allâh Almighty says:
"And whosoever fears Allah and keeps his duty to Him, He will make a way for him to get out (from every difficulty). And He will provide him from (sources) he never could imagine."
For this reason you should supplicate asking Allah Almighty to provide you with lawful, good, and blessed sustenance, for Allah Almighty loves those who persist in their supplications. Allah Almighty said:
"Invoke me, I will respond to your (invocation)."
He Almighty also said:
"And when My servants ask you concerning Me, then (answer them), I am indeed near (to them by My Knowledge). I respond to the invocations of the supplicant when he calls on Me."
