﴿ لِّيُنذِرَ مَن كَانَ حَيًّۭا وَيَحِقَّ ٱلْقَوْلُ عَلَى ٱلْكَٰفِرِينَ ﴾

“to the end that it may warn everyone who is alive [of heart], and that the word [of God] may bear witness against all who deny the truth.”

(To warn) so that Muhammad (pbuh) warns by means of the Qur'an (whosoever liveth) whoever has an intellect, (and that the word) enjoining wrath and punishment (may be fulfilled against the disbelievers) of Mecca such that they do not believe in Muhammad (pbuh) or in the Qur'an.
