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

(181) And We rained down on them a rain (of stones). So evil was the rain of those who were warned.

(182) Is not He (better than your gods) Who created the heavens and the earth, and sends down for you water (rain) from the sky, whereby We cause to grow wonderful gardens full of beauty and delight? It is not in your ability to cause the growth of their trees. Is there any ilah (god) with Allah? Nay, but they are a people who ascribe equals (to Him)!

(183) And whoever brings an evil deed (i.e. Shirk - polytheism, disbelief in the Oneness of Allah and every evil sinful deed), they will be cast down (prone) on their faces in the Fire. (And it will be said to them) "Are you being recompensed anything except what you used to do?"

(184) And you were not expecting that the Book (this Qur'an) would be sent down to you, but it is a mercy from your Lord. So never be a supporter of the disbelievers.

(185) And let them not turn you (O Muhammad صلى الله عليه وسلم) away from (preaching) the Ayat (revelations and verses) of Allah after they have been sent down to you: and invite (men) to (believe in) your Lord and be not of Al-Mushrikun (those who associate partners with Allah, e.g. polytheists, pagans, idolaters, and those who disbelieve in the Oneness of Allah and deny the Prophethood of Messenger Muhammad صلى الله عليه وسلم).

(186) "Verily, we are about to bring down on the people of this town a great torment from the sky, because they have been rebellious (against Allah's Command)."

(187) And thus We have sent down the Book (i.e. this Qur'an) to you (O Muhammad صلى الله عليه وسلم), and those whom We gave the Scripture [the Taurat (Torah) and the Injeel (Gospel) aforetime] believe therein as also do some of these (who are present with you now like 'Abdullah bin Salam) and none but the disbelievers reject Our Ayat [(proofs, signs, verses, lessons, etc.,) and deny Our Oneness of Lordship and Our Oneness of worship and Our Oneness of Our Names and Qualities: i.e. Islamic Monotheism].

(188) And they say: "Why are not signs sent down to him from his Lord? Say: "The signs are only with Allah, and I am only a plain warner."

(189) Is it not sufficient for them that We have sent down to you the Book (the Qur'an) which is recited to them? Verily, herein is mercy and a reminder (or an admonition) for a people who believe .

(190) And if you were to ask them: "Who sends down water (rain) from the sky, and gives life therewith to the earth after its death?" they will surely reply: "Allah." Say: "All the praises and thanks be to Allah!" Nay, most of them have no sense.
