The word(s) "arab" appears 56 time(s) in 49 verse(s) in Quran in Mohsin Khan translation.

(31) And indeed We have set forth for mankind, in this Qur'an every kind of parable. But if you (O Muhammad صلى الله عليه وسلم) bring to them any sign or proof (as an evidence for the truth of your Prophethood), the disbelievers are sure to say (to the believers): "You follow nothing but falsehood, and magic."

(32) And he puts forth for Us a parable, and forgets his own creation. He says: "Who will give life to these bones after they are rotten and have become dust?"

(33) And indeed they (arab pagans) used to say:

(34) And they (arab pagans) wonder that a warner (Prophet Muhammad صلى الله عليه وسلم) has come to them from among themselves. And the disbelievers say: "This (Prophet Muhammad صلى الله عليه وسلم) is a sorcerer, a liar.

(35) An arabic Qur'an, without any crookedness (therein) in order that they may avoid all evil which Allah has ordered them to avoid, fear Him and keep their duty to Him.

(36) A Book whereof the Verses are explained in detail - a Qur'an in arabic for people who know.

(37) And if We had sent this as a Qur'an in a foreign language (other than arabic), they would have said: "Why are not its verses explained in detail (in our language)? What! (A Book) not in arabic and (the Messenger) an arab?" Say: "It is for those who believe, a guide and a healing. And as for those who disbelieve, there is heaviness (deafness) in their ears, and it (the Qur'an) is blindness for them. They are those who are called from a place far away (so they neither listen nor understand)."

(38) And thus We have revealed to you (O Muhammad صلى الله عليه و سلم) a Qur'an in arabic that you may warn the Mother of the Towns (Makkah) and all around it, and warn (them) of the Day of Assembling of which there is no doubt: when a party will be in Paradise (those who believed in Allah and followed what Allah's Messenger صلى الله عليه و سلم brought them) and a party in the blazing Fire (Hell) (those who disbelieved in Allah and followed not what Allah's Messenger صلى الله عليه و سلم brought them).

(39) Verily, We have made it a Qur'an in arabic that you may be able to understand (its meanings and its admonitions).

(40) And if one of them is informed of the news of (the birth of a girl) that which he sets forth as a parable to the Most Gracious (Allah), his face becomes dark, and he is filled with grief!
