在瑞士洛桑市附近有一家专卖伊斯兰教徒朝觐用品的“跪毯公司”,由一位出生于伊拉克的天主教徒约瑟夫·卡莫经营。他发明的“麦加测位仪”,可帮助教徒们在朝觐途中寻觅麦加的方位。卡莫原是苏黎世一家机械公司的雇员。一天,他在苏丹首都喀土穆偶尔见到两个伊斯兰教徒在祈祷时为争辩麦加的方向而几乎动武。 Near the city of Lausanne, Switzerland, there is a “kneeling blanket company” specializing in Islamic hajj items, run by a Catholic Joseph Kamo who was born in Iraq. He invented the “Mecca”, which helps Christians find Mecca during the pilgrimage. Carmo was originally an employee of a mechanical company in Zurich. One day, he occasionally saw in Khartoum, the capital of Sudan, that almost two Muslims used their weapons to pray for the direction of Mecca during their prayers.
