It says in the Holy Quran:
And to Allah alone belong all perfect attributes. (7:181)
He is Allah, and there is no God beside Him, the Knower of the unseen and the seen. He is the Gracious, the Merciful. (59:23)
He is Allah, and there is no God beside Him, the Sovereign, the Holy One, the Source of Peace, the Bestower of Security, the Protector, the Mighty, the Subduer, the Exalted. Holy is Allah, far above that which they associate with Him. (59:24)
He is Allah, the Creator, the Maker, the Fashioner. His are the most beautiful names. All that is in the heavens and the earth glorifies Him, and He is the Mighty, the Wise. (59:25)
There are at least 107 attributes of God either expressly mentioned in the Holy Quran or are deducible from Quranic verses. Each of them is explained in the category Attributes of God. Many more attributes of God, the operation of which is not connected with man, have not been mentioned in the Holy Quran.
