[These letters are one of the miracles of the Qur'ân,
and none but Allâh (Alone) knows their meanings].
(This is) a Book which We have revealed unto you
(O Muhammad SAW)
in order that you might lead mankind out of darkness (of disbelief
and polytheism) into light (of belief in the Oneness of Allâh
and Islâmic Monotheism) by their Lord's Leave to the Path
of the All-Mighty, the Owner of all Praise.
