Anwar was our guide for a tour of Abu Dhabi and the desert area around there.  He gave us so much information about the mosque itself, its culture and religion.  We saw the burial place of Sheikh Zayed himself along with the Mu'adhin reciting the prayers.  Anwar was very kind and patient and a great guide for our tour!  I would definately use him again when we return to Dubai and would recommend him as a guide for your tours of Dubai.
