﴿ فَذَرْهُمْ يَخُوضُوا۟ وَيَلْعَبُوا۟ حَتَّىٰ يُلَٰقُوا۟ يَوْمَهُمُ ٱلَّذِى يُوعَدُونَ ﴾

“But leave them to indulge in idle talk and play [with words] until they face that [Judgment] Day of theirs which they have been promised:”

(So let them) O Muhammad (flounder (in their talk)) of falsehood (and play) and mock the Qur'an (until they meet) until they see (the Day which they are promised) death and punishment.
