Ahmad and Tāwūs «1» said: Whoever is compelled by necessity to eat carrion but refuses to eat until he dies will enter the Fire.
This also includes taking medicine when one is certain that it will save one from death, according to the more correct of the two views. If recovery through it is merely considered likely, is taking it recommended, permissible, or better avoided? There is a well-known disagreement on this among earlier and later scholars.
Forbidden tasting includes drinking wine, consuming lethal poisons, and tasting what is prohibited during an obligatory fast.
Disliked tasting includes consuming things of doubtful permissibility, eating beyond one’s needs, and eating food when one unexpectedly comes upon someone eating who had not intended to invite one to join him. It also includes eating food served for show at wedding feasts, other gatherings, and similar occasions.
The Sunan collections report that the Messenger of Allah (peace and blessings be upon him) “forbade eating the food of those who compete with one another in ostentation.”
It also includes eating the food of someone who feeds you out of embarrassment rather than willingly.
Recommended tasting includes eating lawful food that helps you obey Allah, Mighty and Majestic; eating with a guest so that he feels at ease and eats his fill; and eating the food offered by a host whose invitation it is obligatory or recommended to accept.
Some jurists have held that eating at a wedding feast whose invitation must be accepted is itself obligatory, because the Lawgiver has commanded it.
