= Ayn-Ra-Ba = Arab
muslim atheism, what you spelt here - ayn, ra, ba - عرب - is "Arab"
It says (الْأَعْرَابُ) ... don't twist the word of Allah with your Ajami Arabic.
What you spelt here - alif, lam-alif, ayn, ra, alif, ba - al a'raab. Notice the ayn has sukoon, ie. no vowel, hence the apostrophe in transliteration, and the 2 "a"s after the r, because the second alif is actually madd, which prolongs the fatha ("aaaa" sound).
Two different words, with different pronunciations (tajweed, if you like) and totally different meanings.
