Abraham's reasoning helped to reveal the truth, and then the conflict between him and his people began, for the worshipers of the stars and planets did not stand mute. They began arguing and threatening Abraham.
Abraham replied: "Do you dispute with me concerning Allah while He has guided me, and I fear not those whom you associate with Allah in worship. (Nothing can happen to me) except when my Lord (Allah) wills something. My Lord comprehends in His Knowledge all things. Will you not then remember? And how should I fear those whom you associate in worship with Allah (though they can neither benefit nor harm), while you fear not that you have joined in worship with Allah things for which He has not sent down to you any authority. (So) which of the two parties has more right to be in security? . . . if you but know! It is those who believe (in the oneness of Allah and worship none but Him Alone) and confuse not their belief with Zulm (wrong i.e. by worshipping others besides Allah), for them (only) there is security and they are the guided." Surah 6: 80-82
The curtains are drawn on the first category of people, those who were worshipping celestial bodies. The next situation reveals the second group, those who were practicing idolatry.
