Surah 6. Al-An'am, Ayah 108

This prohibition of reviling anything that other people hold sacred - even in contravention of the principle of God's oneness - is expressed in the plural and is, therefore, addressed to all believers. Thus, while Muslims are expected to argue against the false beliefs of others, they are not allowed to abuse the objects of those beliefs and to hurt thereby the feelings of their erring fellow-men.

Lit., "thus goodly have We made ...", etc., implying that it is in the nature of man to regard the beliefs which have been implanted in him from childhood, and which he now shares with his social environment, as the only true and possible ones - with the result that a polemic against those beliefs often tends to provoke a hostile psychological reaction.

A man's actual personal religion depends upon many things, -his personal psychology, the background of his life, his hidden or repressed feelings, tendencies, or history (which psychoanalysis tries to unravel), his hereditary dispositions or antipathies, and all the subtle influences of his education and his environment. The task before the man of God is: (1) to use any of these which can subserve the higher ends, (2) to purify such as have been misused, (3) to introduce new ideas and modes of looking at things, and (4) to combat what is wrong and cannot be mended: all for the purpose of leading to the truth and gradually letting in spiritual light where there was darkness before. If that is not done with discretion and the skill of a spiritual Teacher, there may be not only a reaction of obstinacy, but an unseemly show of dishonour to the true God and His Truth, and doubts would spread among the weaker brethren whose faith is shallow and infirm. What happens to individuals is true collectively of nations or groups of people. They think in their self-obsession that their own ideas are right. God in His infinite compassion bears with them, and asks those who have purer ideas of faith not to vilify the weaknesses of their neighbours, lest the neighbours in their turn vilify the real truth and make matters even worse than before. In so far as there is active evil, He will deal with it in His own way. Of course the righteous man must not hide his light under a bushel, or compromise with evil, or refuse to establish right living where he has the power to do so.
