Allatheena amanoo walam yalbisoo eemanahum bithulmin ola-ika lahumu al-amnu wahum muhtadoon (surah Anam: 82)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(6:82) Those who believe and did not tarnish their faith with wrong-doing for them there is security, and it is they who have been guided to the right way.' *55

Allazeena aamanoo wa lam yalbisooo eemaanahum bizulmin ulaaa`ika lahumul amnu wa hum muhtadoon

*55). This entire section shows that those people did not deny the existence of God as the creator of the heavens and earth. Their real guilt was that they associated others in His attributes and His rights over man. In the first place, Abraham himself clearly states that they associated others with God as His partners. In the second place, the way in which Abraham mentions God in addressing these people is suitable only for a people who did not deny the existence of God. We must, therefore, regard as incorrect the opinion of those Qur'anic commentators who try to explain this verse on the assumption that the people of Abraham either denied or were unaware of the existence of God, and considered their own deities to be the exclusive possessors of godhead.
The expression 'and did not tarnish their faith with wrong-doing' led some Companions to the misapprehension that perhaps this 'wrong-doing' signified 'disobedience'. But the Prophet (peace be on him) has made it clear that this wrong-doing signifies shirk (associating others with God in His divinity). The verse means, therefore, that they alone are fully secure and rightly-guided who believe in God and do not mix their faith with any polytheistic belief and practice.
It is interesting to learn that this incident, which is the starting-point of Abraham's prophetic career, has found no place in the Bible. It is mentioned only in the Talmud. The Talmudic version, however, is different from the Qur'anic version in two ways. First, in the Talmudic version Abraham's quest for the Truth begins with the sun and then proceeds by way of the stars to his discovery of the One True God. Second. it states that Abraham not only held the sun to be his Lord but even worshipped it, and that the same happened in connection with the moon.
