A picture taken on April 26, 2018 show an Egyptian man manufactures traditional lanterns known in Arabic as "Fanous", ahead of the holy Muslim month of Ramadan in Cairo, Egypt. Ramadan is sacred to Muslims because it is during that month that tradition says the Koran was revealed to the Prophet Mohammed. The fast is one of the five main religious obligations under Islam. Muslims around the world will mark the month, during which believers abstain from eating, drinking, smoking and having sex from dawn until sunset. Photo by Amr Sayed
