Can you please explain it in detail. I don't know Arabic and can't figure out the pattern. He is born in my country and it would be cool to show the cover to my peers.
The pattern is the script called "Square Kufic" (a google image search +mosaic reveals many wondrous examples) and the arabic form of al-Khwarizmi is الخوارزمي
The kufic letters are fairly abstract but look for the verticals, there are 9 letters (last 2 are joined, I think, I cannot read it either just looking closely)
