Surah 6. Al-An'am, Ayah 137

Lit., "their [God-]partners make". As pointed out by Razi, some early commentators were of the opinion that the expression shuraka'uhum (lit., "their associates") denotes here the "evil beings" or "forces" (shayatin) from among men and jinn referred to in verses {112}, {121}, {128} and {130} of this surah. It seems to me, however, that what is meant here - as in the preceding verse - is the belief in the existence of anything that could be "associated" with God; hence my rendering of the above phrase as "their belief in beings or powers that are supposed...", etc.

This is a reference to the custom prevalent among the pre-Islamic Arabs of burying alive some of their unwanted children, mainly girls, and also to the occasional offering of a boy-child in sacrifice to one or another of their idols (Zamakhshari). Apart from this historical reference, the above Qur'an-verse seems to point out, by implication, the psychological fact that an attribution of divinity to anyone or anything but God brings with it an ever-growing dependence on all kinds of imaginary powers which must be "propitiated" by formal and often absurd and cruel rites: and this, in turn, leads to the loss of all spiritual freedom and to moral self-destruction.

I.e., He allows them to behave as they do because He wants them to make use of their reason and of the free will with which He has endowed man.

The false gods and idols -among many nations, including the Arabs -were supposed to require human sacrifices. Ordinarily such sacrifices are revolting to man, but they are made "alluring" -a sacred rite- by Pagan custom, which falsely arrogates to itself the name of religion. Such customs, if allowed, would do nothing but destroy the people who practise them, and make thier religion but a confused bundle of revolting superstitions.
