The one who has praised Himself with perfect Attributes and with the perfection of magnificence and beauty. The one who sent His Messengers and revealed His Books along with signs and clear proofs. The one who testified to the truth of His Messengers by giving them every sign and proof that would certify the truth of what they came with.
“He is Allah, other than whom none has the right to be worshipped. The King, the Holy, as-Salam, the Giver of Security, the Ever-Watcher, the Almighty, the Compeller, the Supreme. Glory be to Allah! [High is He] above all that they associate as partners with Him.”
[al-Hashr (59): 23]
