فَٱتَّخَذْتُمُوهُمْ سِخْرِيًّا حَتَّىٰٓ أَنسَوْكُمْ ذِكْرِى وَكُنتُم مِّنْهُمْ تَضْحَكُونَ
Fattakhaztumoohum sikhriyyan hattaaa ansawkum zikree wa kuntum minhum tadhakoon
But you kept on laughing at them: so intent were you on laughing at them that it made you forget My warning.
But you took them as a joke until they made you forget my remembrance, and you used to laugh at them.
