The word(s) "down" appears 297 time(s) in 269 verse(s) in Quran in Mohsin Khan translation.

(161) But the chiefs of his people who disbelieved said: "He is no more than a human being like you, he seeks to make himself superior to you. Had Allah willed, He surely could have sent down angels. Never did we hear such a thing among our fathers of old.

(162) Have they not pondered over the Word (of Allah, i.e. what is sent down to the Prophet صلى الله عليه وسلم), or has there come to them what had not come to their fathers of old?

(163) (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.

(164) And indeed We have sent down for you Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) that make things plain, and the example of those who passed away before you, and an admonition for those who are Al-Muttaqun (the pious - See V.2:2).

(165) See you not that Allah drives the clouds gently, then joins them together, then makes them into a heap of layers, and you see the rain comes forth from between them; and He sends down from the sky hail (like) mountains, (or there are in the heaven mountains of hail from where He sends down hail), and strikes therewith whom He wills, and averts it from whom He wills. The vivid flash of its (clouds) lightning nearly blinds the sight. [Tafsir At-Tabari].

(166) We have indeed sent down (in this Qur'an) manifest Ayat (proofs, evidence, verses, lessons, signs, revelations, lawful and unlawful things, and the set boundaries of Islamic religion, etc. that make things clear showing the Right Path of Allah). And Allah guides whom He wills to the Straight Path (i.e. to Allah's religion of Islamic Monotheism).

(167) Blessed be He Who sent down the criterion (of right and wrong, i.e. this Qur'an) to His slave (Muhammad صلى الله عليه وسلم) that he may be a warner to the 'Alamin (mankind and jinn).

(168) And they say: "Tales of the ancients, which he has written down: and they are dictated to him morning and afternoon."

(169) Say: "It (this Qur'an) has been sent down by Him (Allah) (the Real Lord of the heavens and earth) Who knows the secret of the heavens and the earth. Truly, He is Oft-Forgiving, Most Merciful."

(170) And they say: "Why does this Messenger (Muhammad صلى الله عليه وسلم) eat food, and walk about in the markets (as we). Why is not an angel sent down to him to be a warner with him?
