From Al-Ghazali on the Ninety-nine Beautiful Names of God
19. Al-Fattah - the Opener is the one by whose providence whatever is closed is opened, and by whose guidance whatever is unclear is disclosed. At times He opens kingdoms for His prophets and removes them from the hands of His enemies, saying: Lo! We have given thee [O Muḥammad] a signal victory (XLVIII:1) [literally: We opened to you a signal opening], and at other times He lifts the veils from the hearts of His holy men, opening to them the gates to the heavenly kingdoms and the beauties of His majesty. So He says: That which [92] Allah opens unto mankind of mercy, none can withhold it (xxxv:2). Whoever has in his hands the keys to the invisible world and the keys to sustenance, it is proper that he be called an opener.
Counsel: Man should yearn to reach a point where the locks to the divine mysteries are opened by his speech, and where he might facilitate by his knowledge what creatures find difficult in religious and worldly affairs, for him to gain a share in the name of opener.
