In Islam, God is believed to have 99 names in the Quran, known as the 99 Names of God (Arabic: أَسْمَاءُ ٱللَّٰهِ ٱلْحُسْنَىٰ‎ ʾasmāʾu llāhi l-ḥusnā, "Beautiful Names of God").

There is no universal agreement among Muslims as to what exactly counts as a name of God, and what does not. Additionally, while some names are only in the Quran, and others are only in the hadith, there are some names which appear in both. Different sources give different lists of the 99 names.[1]

The following list is based on the one found in the 9th century. Other hadith, such as those of al-Bukhari, Sahih Muslim, Ibn Majah, al-Hakim al-Tirmidhi or Ibn ʿAsākir, have variant lists.

Al-Tirmidhi comments on his list: "This (version of the) hadith is gharib [unusual, scarce]; it has been narrated from various routes on the authority of Abu Hurairah, but we do not know of the mention of the Names in the numerous narrations, except this one."
