Lit., "apart from Him". See in this connection 6:148 and the corresponding note [141]. (The arbitrary, unwarranted prohibitions and taboos alluded to in that verse as well as in the present one are discussed in {6:136-153} and explained in my notes.) The derision of God's messages by the deniers of the truth is implied in their questioning His grant of free will to man - that is to say, the ability to choose between right and wrong, which is the basis of all morality.
I.e., the apostles could not force anyone to make the right choice.
The old, old argument: if Allah is All-Powerful, why did He not force all persons to His Will? This ignores the limited Free-will granted to man, which is the whole basis of Ethics. Allah gives man every opportunity of knowing and understanding things, but He does not force him, for that would be against the whole Plan on which our present Life is constituted.
The Pagan Arabs prescribed various arbitrary prohibitions in the matter of meat; see vi. 143-145. These, of course, are not recognised by Islam, which also removed some of the restrictions of the Jewish Law; vi. 146. The general meaning, however, is far wider. Men erect their own taboos and prohibitions, barriers and restrictions, and ascribe them to Religion. This is wrong, and more consonant with Pagan practice than with Islam.
Clear Message: Mubin: in three senses; (1) a Message clear and unambiguous; (2) one that makes all things clear to those who try to understand, because it accords with their own nature as created by Allah; (3) one preached openly and to everyone.
