I was trying to find the meaning of the 99 Names of Allah to put as a link under my imeem icon to make up for not being able to put up the wonderful video, when I foun a website talking about the uses og the 99 Names of Allah. I found a book on it at a bookstore also, but there was no source... This website quotes 3 sources, though I'm not sure how reliable they are larh and there doesn't seem to be any ayat Al-Qur'an or Hadiths quoted... But I'd link to link it up here for you to view it. There is another link to cross-refer to here.

I have put a link to the youtube video and another to the meanings (with pictures as well as ayat Al'Qur'an!) of the 99 Names below the imeem icon btw.

Just something to add from this website:

Passages from the Qur'an on the
Asma al-Husna
The 99 Names of God

And God's alone are the attributes of perfection; invoke Him, then, by these, and stand aloof from all who distort the meaning of His attributes.
Al A'Raf 7:180, tr. Asad

Say: "Invoke God, or invoke the Most Gracious:
by whichever name you invoke Him,
He is always the One -- for His are all the attributes of perfection."
Al Isra 17:110, tr. Asad

Allah is He, other than Whom there is no other god;
Who knows both what is hidden and what can be witnessed;
He is the Most Compassionate and Merciful.
Allah is He, other than Whom there is no other god;
the Sovereign, the One, the Source of Peace,
the Guardian of Faith, the Preserver of Security,
the Exalted, the Compelling, the Supreme.
Glory be to God, beyond any associations.
He is Allah, the Creator, the Evolver, the Bestower of Form.
To Him belong the Most Beautiful Names:
Whatever exists in heaven and earth declares His Praise and Glory.
And He is Exalted in Power, the Wise.
Al Hashr 59:22, tr. Helminski
