Arabs yes, muslims, no. Islam rots your mind, body and soul.
Neither actually..it was popular in both Persia and India before the Arabs played chess. Additionally, the so-called Arabic numeral system was an invention of the Hindus in ancient India. The Ababs borrowed it it and later popularized it in Europe during the Muslim rule in Spain.
Honestly, I can't think of a single thing that Arabs invented. This PC exhibition is just a joke!!
