The Cow - 2:173
He has forbidden you only carrion, blood, pork and what is slaughtered in the name of none but Allah. Whoever is compelled (to eat them) does not commit a sin, provided he does not seek (a way of abuse) and does not exceed the limit. Allah is Forgiving, Merciful.
It is related to those who associate partners forbidding animals:
The Cattle/6:136
"They set aside for Him a share of what Allah has produced, of crops and livestock, and said: "This is Allah´s and this is our partners´". The share of their partners does not reach Allah, but the share of Allah reaches their partners! How evil are their judgment."
The Cattle/6:138
"They said according to their conjecture: "These are untouchable livestock and crops. None but whom We will may eat them."The livestock that are forbidden to be ridden. The livestock on which they did not mention the name of Allah... They attributed (various forbidden things) to Him. He will punish them for their slander."
The Cattle/6:139
"What is in the bellies of those livestock belongs only to our men and is forbidden to our women. If they are stillborn, then they may share them". He will make them pay for this characterization. He is Wise, Knowing."
The Cattle/6:143
"Eight pairs: Two of the sheep and two of the goat. Say: "Has he forbidden the two males or the two females, or what is in the wombs of the two females?"Answer me on the basis of knowledge, if you are truthful."
The Cattle/6:144
"Two of the camel and two of the cattle. Say: "Has He forbidden two males or two females, or what is in the wombs of the two females? And who is more unjust than he who invents lies and attributes them to Allah in order to mislead the people from the way without knowledge? Allah does not guide an unjust people."
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 Cattle/6:148
"Those who associate partners will say: "If Allah had not willed, neither we nor our fathers would have associated partners, nor would we have forbidden anything."And those before them denied in the same way until they tasted Our torment. Say: "Do you have any knowledge with you that you can show us? You follow only conjecture (doubtful and contradictory narrations) and you are only guessing."
The Table Spread/5:103
Allah does not approve of the forbidding of those who have offspring with a certain combination of male and female, of those who are released on oath, of those who give birth to two males in succession, and of male camels who give offspring ten times; the disbelievers slander Allah. Most of them do not understand.
Council/42:21
Or do they have associates who lay down for them religious rules and laws without Allah´s permission? Judgment would have been given between them if there had not been a pre-determined decision. There is a painful torment for the wrongdoers.
The Women/4:119
"I will lead them astray, I will keep them in delusion, I will command them to cut off the ears of animals (so that their meat is forbidden), I will command them to change what Allah has created."Whoever takes Satan as his friend and ruler instead of Allah, he has suffered a manifest loss."
