Amman: The top religious adviser to Jordan's king has thanked Pope Benedict XVI for his expression of "regret" after a 2006 speech that many Muslims deemed insulting to Islam's Prophet Mohammad (PBUH).

Prince Ghazni bin Mohammad says he also appreciated the pope's clarification that the quotes from a Medieval text about Mohammad that he used in the speech did not reflect his personal views.

Ghazni spoke on Saturday after Benedict toured the oldest mosque in Jordan's capital, Amman, his second visit to a Muslim place of worship since becoming pope in 2005.

Benedict told the audience at the mosque that Muslims and Christians must strive to be seen as faithful worshippers of God.

The pope is in Jordan on the second day of a weeklong Mideast visit.
