(Al-Hijr) 15 : 11
وَمَا يَأْتِيهِمْ مِنْ رَسُولٍ إِلَّا كَانُوا بِهِ يَسْتَهْزِئُونَ

And no Messenger had come to them except that they were ridiculing him.

It is told in verse 36: 30: “Alas for the servants. There did not come to them any Messenger except that they used to ridicule him”. All Messengers have been ridiculed by their own people as explained in verse 14: 13. When Fujjar became wrongdoers and transgressors, they were affected by the punishment about what they had been ridiculing.  Impartial Lord doesn’t ruin anyone, but the wrongdoers are doing unjust against themselves as explained in verse 6: 10. It is told in verses 83: 29-34: “Indeed, the Arabic Quran reading Fujjar/Mujirims are mocking at the believers who testifies Adhikr in this world; and whenever they passed them, they used to wink at each other in mockery, and they returned to their own family with joking. And whenever they see the believers, they would say these are the strayed people, but they are not sent as the custodians upon the believers. On the Day of Judgment, the believers will be laughing at these Fujjar and Kuffar”. See explanation 6: 5; 11: 8 and 13: 32.
