None can make Anything Lawful or Unlawful except Allah or Those Whom Allah has allowed to do so
Allah says;
قُلْ أَرَأَيْتُم مَّا أَنزَلَ اللّهُ لَكُم مِّن رِّزْقٍ فَجَعَلْتُم مِّنْهُ حَرَامًا وَحَلَلاً قُلْ اللّهُ أَذِنَ لَكُمْ أَمْ عَلَى اللّهِ تَفْتَرُونَ
Say;"Tell me, what provision Allah has sent down to you! And you have made of it lawful and unlawful."
Say;"Has Allah permitted you (to do so), or do you invent a lie against Allah!"
Ibn Abbas, Mujahid, Ad-Dahhak, Qatadah, Abdur-Rahman bin Zayd bin Aslam and others said;
"This Ayah was revealed to criticize the idolators for what they used to make lawful and unlawful. Like the Bahirah, Sa'ibah and Wasilah."
As Allah said;
وَجَعَلُواْ لِلَّهِ مِمَّا ذَرَأَ مِنَ الْحَرْثِ وَالاٌّنْعَامِ نَصِيباً
And they assign to Allah a share of the tilth and cattle which He has created. (6;136)
Imam Ahmad recorded a narration from Malik bin Nadlah who said,
"I came to Allah's Messenger while in filthy clothes. He said,
هَلْ لَكَ مَالٌ
Do you have wealth?
I answered, `Yes.'
He said,
مِنْ أَيِّ الْمَالِ
what kind of wealth?
I answered, `All kinds; camels, slaves, horses, sheep.'
So he said,
إِذَا اَتَاكَ اللَّهُ مَالاً فَلْيُرَ عَلَيْك
If Allah gives you wealth, then let it be seen on you.
Then he said,
هَلْ تُنْتَجُ إِبْلُكَ صِحَاحًا اذَانُهَا فَتَعْمِدَ إِلَى مُوسًى فَتَقْطَعَ اذَانَهَا فَتَقُولُ هَذِهِ بُحْرٌ وَتَشُقُّ جُلُودَهَا وَتَقُولُ هَذِهِ صُرُمٌ وَتُحَرِّمُهَا عَلَيْكَ وَعَلَى أَهْلِك
It is not that your camels are born with healthy ears, you take a knife and cut them, then say, "This is a Bahr," tear its skin, then say, `This is a Sarm," and prohibit them for yourself and your family.
I replied, `Yes.' He said,
فَإِنَّ مَا اتَاكَ اللهُ لَكَ حِلٌّ سَاعِدُ اللهِ أَشَدُّ مِنْ سَاعِدِكَ وَمُوسَى الله أَحَدُ مِنْ مُوسَاك
What Allah has given you is lawful. Allah's Forearm is stronger than your forearm, and Allah's knife is sharper then your knife."
And he mentioned the Hadith in its complete form, and the chain for this Hadith is a strong, good chain.
Allah criticized those who make lawful what Allah has made unlawful or vice verse. This is because they are based on mere desires and false opinions that are not supported with evidence or proof.
Allah then warned them with a promise of the Day of Resurrection. He asked
