Al Akhir – The Last

He whose existence has no end. The only one being who will remain for ever, even after everything is annihilated.

And call not, besides Allah, on another god. There is no god but He. EVERYTHING (THAT EXISTS) WILL PERISH EXCEPT HIS OWN FACE. To Him belongs the Command, and to Him will ye (all) be brought back.

(28:88) The Holy Quran

“He is the First (al-Awwal) and the Last (al-ākhir), the Ascendant and the Intimate, and He is, of all things, Knowing.” ( The Holy Qur’an 57:3)

From the root a-kh-r which has the following classical Arabic connotations:to put back, to put behind, 
to be latter
to postpone, to put at the end
to be last, final, ultimate

“When you ponder the order of existence and consider the ordered chain of beings, God the most high is first with respect to it… Whenever you ponder the order of wayfaring and observe the states attained by those journeying towards Him, He is the last, for He is the final point to which the levels of the ‘knowers’ ascend…. the first beginning was from Him; and to Him is the return and destination.” Al Ghazali

“He who is illumined at the beginning is illumined at the end.”
Ibn Ata’illah
