Rest assured!
Do not be concerned about what Allah Almighty has guaranteed for you for He describes Himself as the Keeper and the All-Provider.
“Al-Muqīt” is more specific than “Ar-Razzāq”, for Al-Muqīt gives us food that nourishes our bodies, while Ar-Razzāq gives us all what we possess, food and everything else.
As long as we are alive, sustenance and provision will surely come to us. If, out of His wisdom, He closes a certain door before you, He o
pens another, out of His mercy.
Think about the fetus. Its sustenance, which is blood, reaches it through one way: the navel. Then, after it comes out of its mother’s womb, this way is severed and two other ways are opened for him in its place, through which better and more pleasant sustenance comes: pure and palatable milk. Then, after the phase of suckling is over, four new ways open for him, from which he gets two kinds of food and two kinds of drink. The two kinds of food come from animals and plants, whereas the two kinds of drink are water and milk.
Then, after he dies, these four ways are closed and the eight gates of Paradise are opened for the believers and they can enter from whichever gate they wish.
