Names of God in Islam ( , "Allah's Beautiful Names") are names attributed to God in Islam by Muslims. While some names are only in the Quran, and others are only in the hadith, Some names which appear in both the hadith literature and the Qur'an. List Hadith By what they said to Sahih Bukhari Hadith: There is another Sahih Muslim Hadith: The Quran refers to God's Most Beautiful Names (al-ʾasmāʾ al-ḥusná) in several Surahs.
