The Cattle - 6:118
Eat of that on which Allah´s Name is mentioned, if you believe in His Verses.
Haram substances:
The Table Spread/5:3
Forbidden to you are carrion, blood, the flesh of swine and what is dedicated to none but Allah. Except that you slaughter them before they are dead, animals that have been strangled, shot, fallen, gored and eaten by beasts, and those slaughtered on sacred stones and distributed with fortune-telling arrows, yes, these are evil. The unbelievers have despaired of your religion today. Do not fear them; fear Me. Today I have perfected your religion for you, I have completed My blessing upon you, and I have chosen Islam as your religion. Whoever is in hardship because of hunger and eats without any temptation to sin, there is no sin on him. For Allah is Forgiving, Merciful.
The Cattle/6:145
"Say: "I do not find in what has been revealed to me anything forbidden for anyone who eats, except: carrion, spilled blood, the flesh of swine, which is unclean, and food devoted to none but Allah."And if anyone who is in hardship does not overstep the limit, then surely your Lord is Forgiving, Merciful."
The Bee/16:115
He has forbidden you only carrion, blood, pork and that which is dedicated to none but Allah. And whoever is compelled to eat them, Allah is Forgiving, Merciful, provided he does not desire them and does not exceed the limit.
