While there is some dispute over the exact number, the Qur'an uses 99 names/titles for God. These are known as 'The 99 Names of Allah'; there are a lot of decorations you can buy that have all of the names listed (in arabic). It's impossible for our small human minds to fully comprehend God's attributes, but I think there is some benefit in reflecting on them, so I'll post all 99 of them here. The transliteration of the arabic words are listed first and the english translation are in brackets.
