The word(s) "9" appears 21 time(s) in 19 verse(s) in Quran in Mohsin Khan translation.

(11) On the Day they will see the angels - no glad tidings will there be for the Mujrimun (criminals, disbelievers, polytheists, sinners) that day. And they (angels) will say: "All kinds of glad tidings are forbidden to you," [none will be allowed to enter Paradise except the one who said: La ilaha illallah, "(none has the right to be worshipped but Allah) and acted practically on its legal orders and obligations. See the footnote of V.2:193)].

(12) And when he attained his full strength, and was perfect (in manhood), We bestowed on him Hukm (Prophethood and right judgement of the affairs) and religious knowledge [of the religion of his forefathers i.e. Islamic Monotheism]. And thus do We reward the Muhsinun (i.e. good doers. See the footnote of V.9:120).

(13) They shall have all that they will desire with their Lord. That is the reward of Muhsinun (good-doers - see the footnote of V.9:120).

(14) Verily, those who disbelieved in the Reminder (i.e. the Qur'an) when it came to them (shall receive the punishment). And verily, it is an honourable well-fortified respected Book (because it is Allah's Speech, and He has protected it from corruption. (See V.15:9)

(15) And say: "Are our alihah (gods) better or is he ['Îsa (Jesus)]?" They quoted not the above example except for argument. Nay! But they are a quarrelsome people. (See V. 21:98-101)

(16) 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].

(17) And before this was the Scripture of Musa (Moses) as a guide and a mercy. And this is a confirming Book (the Qur'an) in the Arabic language, to warn those who do wrong, and as glad tidings to the Muhsinun (good-doers. See the footnote of V.9:120).

(18) And We have set none but angels as guardians of the Fire. And We have fixed their number (19) only as a trial for the disbelievers, in order that the people of the Scripture (Jews and Christians) may arrive at a certainty [that this Qur'an is the truth as it agrees with their Books regarding the number (19) which is written in the Taurat (Torah) and the Injeel (Gospel)] and that the believers may increase in Faith (as this Qur'an is the truth), and that no doubt may be left for the people of the Scripture and the believers, and that those in whose hearts is a disease (of hypocrisy) and the disbelievers may say: "What Allah intends by this (curious) example ?" Thus Allah leads astray whom He wills and guides whom He wills. And none can know the hosts of your Lord but He. And this (Hell) is nothing else than a (warning) reminder to mankind.

(19) But it will be only a single Zajrah [shout (i.e., the second blowing of the Trumpet)], (See Verse 37:19).
