(Al Qamar) 54 : 18
كَذَّبَتْ عَادٌ فَكَيْفَ كَانَ عَذَابِي وَنُذُرِ
Aad rejected; then how were My punishment and Warnings?
The Message brought through Messenger Hood was also Adhikr. When the people of Hood—the Aad people—became transgressors by hiding and rejecting Adhikr, they were destroyed. See explanation 46: 35; and 53: 56.
