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

(131) And with truth We have sent it down (i.e. the Qur'an), and with truth it has descended. And We have sent you (O Muhammad صلى الله عليه و سلم) as nothing but a bearer of glad tidings (of Paradise for those who follow your Message of Islamic Monotheism), and a warner (of Hell-fire for those who refuse to follow your Message of Islamic Monotheism) .

(132) Say (O Muhammad صلى الله عليه و سلم to them): "Believe in it (the Qur'an) or do not believe (in it). Verily those who were given knowledge before it (the Jews and the Christians like 'Abdullah bin Salam and Salman Al-Farisi), when it is recited to them, fall down on their faces in humble prostration."

(133) And they fall down on their faces weeping and it increases their humility.

(134) All the praises and thanks be to Allah, Who has sent down to His slave (Muhammad صلى الله عليه وسلم) the Book (the Qur'an), and has not placed therein any crookedness.

(135) And put forward to them the example of the life of this world: it is like the water (rain) which We send down from the sky, and the vegetation of the earth mingles with it, and becomes fresh and green. But (later) it becomes dry and broken pieces, which the winds scatter. And Allah is Able to do everything.

(136) (Dhul-Qarnain) said: "This is a mercy from my Lord, but when the Promise of my Lord comes, He shall level it down to the ground. And the Promise of my Lord is ever true."

(137) Those were they unto whom Allah bestowed His Grace from among the Prophets, of the offspring of Adam, and of those whom We carried (in the ship) with Nuh (Noah), and of the offspring of Ibrahim (Abraham) and Israel, and from among those whom We guided and chose. When the Verses of the Most Gracious (Allah) were recited unto them, they fell down prostrate and weeping.

(138) And We shall drive the Mujrimun (polytheists, sinners, criminals, disbelievers in the Oneness of Allah) to Hell, in a thirsty state (like a thirsty herd driven down to water).

(139) We have not sent down the Qur'an unto you (O Muhammad صلى الله عليه وسلم) to cause you distress,

(140) He said: "This is my stick, whereon I lean, and wherewith I beat down branches for my sheep, and wherein I find other uses."
