The word(s) "arabic" appears 12 time(s) in 11 verse(s) in Quran in Mohsin Khan translation.

(1) Verily, We have sent it down as an arabic Qur'an in order that you may understand.

(2) And thus have We sent it (the Qur'an) down to be a judgement of authority in arabic. Were you (O Muhammad صلى الله عليه و سلم) to follow their (vain) desires after the knowledge which has come to you, then you will not have any Wali (protector) or Waq (defender) against Allah.

(3) And indeed We know that they (polytheists and pagans) say: "It is only a human being who teaches him (Muhammad صلى الله عليه و سلم)." The tongue of the man they refer to is foreign, while this (the Qur'an) is a clear arabic tongue.

(4) And thus We have sent it down as a Qur'an in arabic, and have explained therein in detail the warnings, in order that they may fear Allah, or that it may cause them to have a lesson from it (or to have the honour for believing and acting on its teachings).

(5) In the plain arabic language.

(6) 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.

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

(8) 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)."

(9) 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).

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