Determine of Halal and Haram

Islam has given an authority to determine the limits of haram and halal, by releasing these rights from a human hand, no matter how high the human position in the field of religion and the position of the world. Rights determine the of halal and haram is solely in the hands of God. Rights of determine the halal and haram not on a priest, not on a king. Who's doing that, it means he has trespassed and oppose God in establishing legislation to mankind. And who accept and follow these attitudes, these meaning he make them priests and kings as an ally of God, while his followers called musyrik.

"Do they have any gods besides God who made the law to their religion are not allowed to Allah? Had no statutes that determines (from Allah) they would have been destroyed. and Lo! those who do wrong will get a very painful punishment. "(Ash-Shura (42): 21)

"They make their goody people and their monks as a god but Allah *] and (they also deify) Al Masih (Jesus) the son of Mary, yet they are told to worship only one God, there is no god (worthy of worship) but Him. Most holy God from what they associate. "(Al-Tawbah (9): 31)

*] The point is: they adhere to the teachings of pious people and monks them blindly, even pious people and monks were ordered made immoral or forbidden the halal.

Allah in the Qur'an also has to give a decision to the idolaters who had dared to proscribe and justifies without the permission of God, as stated in (Yunus (10): 59)

"Say:" Explain to me about the sustenance which Allah revealed to you, then you make part Haram and (some things) halal. "Say: "Did God has given you permission (about this) or you invent a course toward God?"
From some of the basis of the above scholars know with certainty that only God has the right to determine the haram and halal things. Goody People tasks is to explain God's laws of halal and haram it.
