Quran: The Ultimate Reference
5:48 Then we revealed to you this scripture, truthfully, confirming previous scriptures, and superseding them. You shall rule among them in accordance with GOD’s revelations, and do not follow their wishes if they differ from the truth that came to you. For each of you, we have decreed laws and different rites. Had GOD willed, He could have made you one congregation. But He thus puts you to the test through the revelations He has given each of you. You shall compete in righteousness. To GOD is your final destiny—all of you—then He will inform you of everything you had disputed.

Religious Innovations Condemned
6:138 They said, “These are livestock and crops that are prohibited; no one shall eat them except whomever we permit,” so they claimed. They also prohibited the riding of certain livestock. Even the livestock they ate, they never pronounced GOD’s name as they sacrificed them. Such are innovations attributed to Him. He will surely requite them for their innovations. 6:139 They also said, “What is in the bellies of these livestock is reserved exclusively for the males among us, and prohibited for our wives.” But if it was a stillbirth, they permitted their wives to share therein. He will certainly requite them for their innovations. He is Most Wise, Omniscient.
5:103 GOD did not prohibit livestock that begets certain combinations of males and females, nor livestock liberated by an oath, nor the one that begets two males in a row, nor the bull that fathers ten. It is the disbelievers who invented such lies about GOD. Most of them do not understand.
5:4 They consult you concerning what is lawful for them; say, “Lawful for you are all good things, including what trained dogs and falcons catch for you.” You train them according to GOD’s teachings. You may eat what they catch for you, and mention GOD’s name thereupon. You shall observe GOD. GOD is most efficient in reckoning.
28:57 They said, “If we follow your guidance, we will suffer persecution.” Did we not establish for them a Sacred Sanctuary, to which all kinds of fruits are offered, as a provision from us? Indeed, most of them do not know.
3:123 GOD has granted you victory at Badr, despite your weakness. Therefore, you shall observe GOD, to show your appreciation.
According to 22:36 is it necessary that the livestock you sacrifice during Hajj that you need to eat and feed the poor with the meat? From experience a lot of times they sacrifice the animal but since there is so much people converging on such a short amount of time they end up wasting the meat.
