Arab is an ethnicity, not a religion. Therefore there is no place of worship which is suitable for all Arabs.
Most Arabs are Muslims and therefore pray in Mosques, but some Arabs are Christian and pray in Churches. Additionally, some Arabs are Jewish, Zoroastrian, Baha'i, Druze, and Yazidi, which leads to them praying in distinct houses of worship for those religions. Finally, some Arabs (although few are vocal about it) are Atheists and therefore do not worship at all.

I assume that by "Arab man's headscarf" you are referring to the keffiyeh (like what Yasser Arafat wore). It is either held in place by internal knots in the fabric or by a black ringlet called an aqaal.
There are no holy Arab men or women. Holiness in Islam is only for God; the one and only one God with no partner, son, or father; and His books revealed to his prophets including the Psalms, Torah, Bible, and Quran.
Most of them worship Allah (sp), which is the religion Islam.
