وَكَيْفَ أَخَافُ مَآ أَشْرَكْتُمْ وَلَا تَخَافُونَ أَنَّكُمْ أَشْرَكْتُم بِٱللَّهِ مَا لَمْ يُنَزِّلْ بِهِۦ عَلَيْكُمْ سُلْطَٰنًۭا ۚ فَأَىُّ ٱلْفَرِيقَيْنِ أَحَقُّ بِٱلْأَمْنِ ۖ إِن كُنتُمْ تَعْلَمُونَ
How should I fear that which ye set up beside Him, when ye fear not to set up beside Allah that for which He hath revealed unto you no warrant? Which of the two factions hath more right to safety? (Answer me that) if ye have knowledge.
