On the inside of the entrance arc there's a geometric pattern in which kufic script is included.[br]The pattern is created by octagons and squares. Focussing on one octagon, you can see that in it 8 squares are arranged around an 8-pointed star.[br]In the filling of the squares you can read Allah akhbar.

The 8-pointed star in the middle of the octagon is the [url=https://en.wikipedia.org/wiki/Rub_el_Hizb]Rub el Hizb[/url]. The star is generated by two overlapping squares.

De combinatie [i]Allah akhbar[/i] in kufisch schrift vind je verder terug in het gebogen vlak van de boog zelf en in zijpanelen van de iwan. [br]Waar ze op de zijwand van de inkomport gerangschigt staan rond een 8-puntige ster, staan ze in de zijpanelen binnen een 8-puntige ster.
