salaam, i want to know for example im in a dessert and im hungry and there is a pig in sight will i be able to eat it? im sorry i have been asked this question by a non muslim

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

It is permissible for whoever does not find food to eat and fears to die–whether he is in the desert or else– to eat pork just to allay his hunger and save himself from death. The evidence about this is the saying of Allaah (which means): {He has forbidden you only the dead animals, and blood, and the flesh of swine, and that which is slaughtered as a sacrifice for others than Allaah (or has been slaughtered for idols, etc., on which Allaah's Name has not been mentioned while slaughtering).But whoever is forced [by necessity], neither desiring [it] nor transgressing [its limit], there is no sin upon him. Truly, Allaah is Oft-Forgiving, Most Merciful.}[Quran 2:173] Allaah also Says (what means): {…while He has explained in detail to you what He has forbidden you, excepting that to which you are compelled.}[Quran 6:119]

Allaah Knows best.
