(Al Qamar) 54 : 16
فَكَيْفَ كَانَ عَذَابِي وَنُذُرِ
Then how were My punishment and warnings?
Just like the Fujjar Mujirims who became wrongdoers and transgressors by hiding and rejecting Adhikr, which is revealed to warn the entire worlds, when other people belonging to the Messenger’s community also become wrongdoers and transgressors, the Doomsday will happen. See explanation 9: 5, 123; and 50: 36-37.
