وَكَيْفَ اَخَافُ مَآ اَشْرَكْتُمْ وَلَا تَخَافُوْنَ اَنَّكُمْ اَشْرَكْتُمْ بِاللّٰهِ مَا لَمْ يُنَزِّلْ بِهٖ عَلَيْكُمْ سُلْطٰنًا ۗفَاَيُّ الْفَرِيْقَيْنِ اَحَقُّ بِالْاَمْنِۚ اِنْ كُنْتُمْ تَعْلَمُوْنَۘ ( الأنعام: ٨١ )
Wa kaifa akhaafu maaa ashraktum wa laa takhaafoona annakum ashraktum billaahi maa lam yunazzil bihee 'alaikum sultaanaa; fa aiyul fareeqaini ahaqqu bil amni in kuntum ta'lamoon (al-ʾAnʿām 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?" (Al-An'am  : 81)
1 Mufti Taqi Usmani
How can I fear that which you associate with Him, while you do not fear (the evil fate of) your having associated with Allah something for which He did not send down to you any authority? Now, which of the two parties has more right to be in peace? (Tell me) if you know.
