The word(s) "arab" appears 23 time(s) in 23 verse(s) in Quran in Muhammad Pickthal translation.

(21) Say unto those of the wandering arabs who were left behind: Ye will be called against a folk of mighty prowess, to fight them until they surrender; and if ye obey, Allah will give you a fair reward; but if ye turn away as ye did turn away before, He will punish you with a painful doom.

(22) The wandering arabs say: We believe. Say (unto them, O Muhammad): Ye believe not, but rather say "We submit," for the faith hath not yet entered into your hearts. Yet, if ye obey Allah and His messenger, He will not withhold from you aught of (the reward of) your deeds. Lo! Allah is Forgiving, Merciful.

(23) And there is none comparable unto Him.
