the permission of an "infidel"? ruler was not what Islám enjoined.
In Turkey and Egypt, and in other countries under Muslim rule, it is the custom for the Khatíb to deliver the Khutbah whilst he holds a wooden sword reversed.
The prayer for the reigning monarch, if he be a Muslim, would be offered up in the following manner:—
"O God, aid Islám, and strengthen its pillars, and make infidelity to tremble, and destroy its might, by the preservation of Thy servant, and the son of Thy servant, the submissive to the might of Thy Majesty and Glory, whom God hath aided, our master Amír Sher ʾAlí Khán, son of Amír Dost Muhammad Khán, may God assist him and prolong his reign. O God, assist him, and assist his armies. O Thou God of the religion and Lord of the world, assist the armies of Muslims; frustrate the armies of infidels and polytheists, thine enemies, the enemies of the religion."
