The Light - 24:21
O you who believe, do not follow the steps of Satan. Whoever follows the steps of Satan, he commands to himself immorality and evil. Had it not been for Allah´s grace and mercy upon you, none of you would have been purified for ever. But Allah purifies those who will. Allah is All-Hearing, All-Knowing.
Creating and following halal and haram outside the Qur'an is following the steps of Shaytan:
The Cattle/6:142
The livestock are for you to ride or slaughter or to make bedding from them. Eat of what Allah has provided for you and do not follow the steps of Satan, for he is your manifest enemy.
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."
The Table Spread/5:88
Eat what Allah has given you as sustenance, lawful and pure. Listen to Allah in whom you believe.
The Cattle/6:118
Eat of that on which Allah´s Name is mentioned, if you believe in His Verses.
The Cattle/6:119
What is the matter with you that you do not eat of that on which Allah´s Name is mentioned, whereas He has explained to you in detail what is forbidden to you except in cases of necessity. Many mislead the people with their personal opinions which are not based on knowledge. Your Lord knows best those who transgress.
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/6:140
Those who slander Allah in their ignorance and kill their children foolishly and forbid what Allah has provided for them, have lost, they are lost. They cannot see the truth.
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 Cattle/6:149
"Say: "The strongest proof is from Allah. If He willed, He would surely guide you all to the truth."
The Cattle/6:150
"Say: "Bring your witnesses to testify that Allah has forbidden this and that."If they testify, do not testify with them. Do not follow the pleasure of those who deny Our Verses and do not believe in the Hereafter. They associate others with their Lord."
Prophet Jonah/10:59
"Say, "Do you not see that of the sustenance which Allah has sent down to you, some of it is lawful and some of it is unlawful?"Say, "Did Allah give you permission, or do you slander Allah?"
The Bee/16:35
Those who associate partners, if Allah had not willed, neither we nor our ancestors would have served anything besides Him, nor would we have forbidden anything besides what He has forbidden. So did those before them. Does the messenger have any duty other than to make clear?
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.
The Bee/16:116
"Do not say: "This is lawful and that is unlawful"because your tongues have falsely characterized it. Thus you ascribe a lie to Allah. Those who ascribe lies to Allah will not succeed."
The Light/24:21
O you who believe, do not follow the steps of Satan. Whoever follows the steps of Satan, he commands to himself immorality and evil. Had it not been for Allah´s grace and mercy upon you, none of you would have been purified for ever. But Allah purifies those who will. Allah is All-Hearing, All-Knowing.
