Muhammad Salah, or Abu Rajab as his mates call him, is what you might call a ‘firebrand cleric’. Even, possibly, a ‘religious zealot’. Some may go so far as to label him a ‘terrorist’, a term he himself seems to have no trouble with. Rajab’s schtick is to liven up his sermons – delivered from the pulpit of the popular Al Abrar mosque in the Gaza/Egypt bordertown of Rafah – with the occasional prop.
