كَلَّا لَئِن لَّمْ يَنتَهِ لَنَسْفَعًا بِالنَّاصِيَةِ (15)
(96:15) No indeed; *12 if he does not desist, We shall drag him by the forelock;
*12) That is, the person who threatens that he would trample the neck of Muhammad (upon whom be Allah's peace and blessings) down when he performed the Prayer, would never be able to do so.
