(Al-Muaminoon) 23 : 110
فَاتَّخَذْتُمُوهُمْ سِخْرِيًّا حَتَّىٰ أَنْسَوْكُمْ ذِكْرِي وَكُنْتُمْ مِنْهُمْ تَضْحَكُونَ
But you took them in mockery until you forget the Book Dhikree, and you used to laugh at them.
It is told in verse 83: 29 that the Fujjar Mujirims used to ridicule the believers who testify Adhikr. So, on the Day of Judgment, the believers will ridicule back the Fujjar as explained in verse 2: 212. See explanation 15: 2; 18: 101 and 23: 66-68.
