The word(s) "surah" appears 11 time(s) in 10 verse(s) in Quran in Mohsin Khan translation.

(1) And if you (Arab pagans, Jews, and Christians) are in doubt concerning that which We have sent down (i.e. the Qur'an) to Our slave (Muhammad صلى الله عليه وسلم), then produce a surah (chapter) of the like thereof and call your witnesses (supporters and helpers) besides Allah, if you are truthful.

(2) The hypocrites fear lest a surah (chapter of the Qur'an) should be revealed about them, showing them what is in their hearts. Say: "(Go ahead and) mock! But certainly Allah will bring to light all that you fear."

(3) And when a surah (chapter from the Qur'an) is revealed, enjoining them to believe in Allah and to strive hard and fight along with His Messenger, the wealthy among them ask your leave to exempt them (from Jihad) and say, "Leave us (behind), we would be with those who sit (at home)."

(4) And whenever there comes down a surah (chapter from the Qur'an), some of them (hypocrites) say: "Which of you has had his Faith increased by it?" As for those who believe, it has increased their Faith, and they rejoice.

(5) And whenever there comes down a surah (chapter from the Qur'an), they look at one another (saying): "Does any one see you?" Then they turn away. Allah has turned their hearts (from the light) because they are a people that understand not.

(6) Or do they say: "He (Muhammad صلى الله عليه وسلم) has forged it?" Say: "Bring then a surah (chapter) like unto it, and call upon whomsoever you can besides Allah, if you are truthful!"

(7) Or they say, "He (Prophet Muhammad صلى الله عليه و سلم) forged it (the Qur'an)." Say: "Bring you then ten forged surahs (chapters) like unto it, and call whomsoever you can, other than Allah (to your help), if you speak the truth!"

(8) (This is) a surah (chapter of the Qur'an) which We have sent down and which We have enjoined, (ordained its laws); and in it We have revealed manifest Ayat (proofs, evidence, verses, lessons, signs, revelations - lawful and unlawful things, and set boundaries of Islamic Religion), that you may remember.

(9) We sent it (this Qur'an) down on a blessed night [(i.e. night of Al-Qadr, surah No. 97) in the month of Ramadan - the 9th month of the Islamic calendar]. Verily, We are ever warning [mankind that Our Torment will reach those who disbelieve in Our Oneness of Lordship and in Our Oneness of worship].

(10) Those who believe say: "Why is not a surah (chapter of the Qur'an) sent down (for us)? But when a decisive surah (explaining and ordering things) is sent down, and fighting (Jihad - holy fighting in Allah's cause) is mentioned (i.e. ordained) therein, you will see those in whose hearts is a disease (of hypocrisy) looking at you with a look of one fainting to death. But it was better for them (hypocrites, to listen to Allah and to obey Him).
