(Those who wrangle concerning the revelations of Allah) those who deny Muhammad (pbuh) and the Qur'an (without any warrant) without any proof (that hath come unto them) from Allah; the reference here is to Abu Jahl and his host who mocked the Prophet, (it is greatly hateful in the sight of Allah) on the Day of Judgement (and in the sight of those who believe) in the life of this world. (Thus doth Allah print on every arrogant) who is too proud to accept faith, (disdainful heart) of accepting the Truth and guidance.
