 There are five times in a day when a foreigner like myself tries to stay off the streets of Cairo. That's at dawn, noon, late afternoon, sunset, and just after dusk, when the Moisan appears in his minaret to call the faithful to prayer. At that moment, all activity stops, and the devout Moslem kneels on his rug, facing Mecca. Keeping away from them at those times is one respect we can pay their religion, and they appreciate that respect.
