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

(11) In plain arabic speech.

(12) And if We had revealed it unto one of any other nation than the arabs,

(13) They hold that the clans have not retired (for good); and if the clans should advance (again), they would fain be in the desert with the wandering arabs, asking for the news of you; and if they were among you, they would not give battle, save a little.

(14) A Lecture in arabic, containing no crookedness, that haply they may ward off (evil).

(15) A Scripture whereof the verses are expounded, a Lecture in arabic for people who have knowledge,

(16) And if We had appointed it a Lecture in a foreign tongue they would assuredly have said: If only its verses were expounded (so that we might understand)? What! A foreign tongue and an arab? - Say unto them (O Muhammad): For those who believe it is a guidance and a healing; and as for those who disbelieve, there is a deafness in their ears, and it is blindness for them. Such are called to from afar.

(17) And thus We have inspired in thee a Lecture in arabic, that thou mayst warn the mother-town and those around it, and mayst warn of a day of assembling whereof there is no doubt. A host will be in the Garden, and a host of them in the Flame.

(18) Lo! We have appointed it a Lecture, in arabic that haply ye may understand.

(19) When before it there was the Scripture of Moses, an example and a mercy; and this is a confirming Scripture in the arabic language, that it may warn those who do wrong and bring good tidings for the righteous.

(20) Those of the wandering arabs who were left behind will tell thee: Our possessions and our households occupied us, so ask forgiveness for us! They speak with their tongues that which is not in their hearts. Say: Who can avail you aught against Allah, if He intend you hurt or intend you profit? Nay, but Allah is ever Aware of what ye do.
