Our existence itself is a great bounty from Allah who created us, out of His Mercy and Grace on us. He created us after we were nothing ( Has here not been over man a time, when he was not a thing worth mentioning?) (Sura 76, Verse 1).
He provided us not only with life but also with all what require to live a decent life e.g. He gifted us with the intellect and reason and ability to listen, see, and distinguish good from bad. He gifted us will all sense which make us enjoy our life and be away from danger. He showed us the best way to live our life with harmony and peace between ourselves and our desires and wishes, and between ourselves and our Creator, and between ourselves and the Universe.
What ever bounty we have is from Him, and what ever suffering we may have is from ourselves.(Whatever good reaches you is from Allah, and whatever bad comes to ou is from yourself). (Sura 4, Verse 79).
He guided us to live in the best way away from evil and sinful desires. Those who follow the way of Allah (SWT) enjoy life in the best way as that achieve the Peace of Mind and Tranquility which is lost in he life of millions who are away from Allah.
We are unable to thank Him enough but when we try to thank Allah for His countless bounties, we feel the taste of life and feel more peace in our hearts.
