And how should I fear what you associate while you do not (6:81)

﴿وَكَيْفَ أَخَافُ مَا أَشْرَكْتُمْ وَلَا تَخَافُونَ أَنَّكُمْ أَشْرَكْتُم بِاللَّهِ مَا لَمْ يُنَزِّلْ بِهِ عَلَيْكُمْ سُلْطَانًا ۚ فَأَيُّ الْفَرِيقَيْنِ أَحَقُّ بِالْأَمْنِ ۖ إِن كُنتُمْ تَعْلَمُونَ﴾
[ الأنعام: 81]

6:81 And how should I fear what you associate while you do not fear that you have associated with Allah that for which He has not sent down to you any authority? So which of the two parties has more right to security, if you should know?

How can I be fearful of the idols you worship besides Allah when you have no fear of your associating as partners with Allah things that He created, without having any proof for doing so? Which of the two groups, the monotheists or the idolaters, is more deserving of safety and security? If you know which group is more deserving, then follow that group.
The more deserving group is undoubtedly the group of the believers who are monotheists.

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."
