(Say) O Muhammad to al-Nadr Ibn al-Harith and his folk: (I am (relying) on clear proof from my Lord) and I have full insight of my matter and religion, (while you deny Him) you deny the Qur'an and Allah's divine Oneness. (I have not that for which ye are impatient) i.e. your punishment. (The decision) to send a punishment on you (is for Allah only. He telleth the Truth) His judgement is just and He commands only that which is right (and He is the Best of Deciders) the best of Judges.
