﴿ مُسْتَكْبِرِينَ بِهِۦ سَٰمِرًۭا تَهْجُرُونَ ﴾

“[and,] impelled by your arrogance, you would talk senselessly far into the night.””

(In scorn thereof) feeling haughty because of the Holy House, claiming that you are its guardians. (Nightly did you rave together) you cursed Muhammad (pbuh) his Companions and the Qur'an in your nightly gatherings.
