This book contains 99 names of God and their meanings. There is a hadith which says, "To God belonfs ninety-nine names." So that while any two lists add up to more than ninety-nine names, any one list is limited to this number. The names are revealed directly in al-Qur'an, or from the meaning given in certain passages, or they are names that are traditionally known, but are not in al-Qur'an. Some names are derived from the Arabic grammar of the names in al-Qur'an, but are not widely accepted.
