…Sustenance/Provision is guaranteed
Ibn Al-Qayyim (رحمه الله تعالى) said:
Concern yourself with that which you were ordered to take care of, and do not be concerned with something that was guaranteed for you. Sustenance and the moment of death are two matters whereof there is no doubt. As long as one is living, sustenance is guaranteed. And if Allaah, according to His wisdom, closed the way to some means, He will, according to His mercy, open another means for you, which will be more useful.
Let us consider the state of the embryo. It receives its nourishment, which is blood from one means, which is the navel, and when it comes out from its mother’s womb and this means is closed, another two means are opened to it, which are better and sweeter than the first! This second means is pure and nourishing milk. When he finishes his suckling period and these two means are closed due to weaning, Allaah opens four more perfect means; two kinds of food and two kinds of drinks. The two foods are from animals and plants and the two drinks are from water and milk, as well as whatever he likes from among other pleasures. When he passes away, his four means are closed but Allaah, the Exalted will open to him, if he was pious, eight doors of Paradise in order to enter Paradise from anyone of them. So we notice that whenever Allaah, the Exalted prevents His believing servant from something during this worldly life, He will bestow upon him something which is better and more useful to him…
