The word(s) "down" appears 165 time(s) in 160 verse(s) in Quran in Muhammad Pickthal translation.

(131) And of His portents (is this): that thou seest the earth lowly, but when We send down water thereon it thrilleth and groweth. Lo! He Who quickeneth it is verily the Quickener of the Dead. Lo! He is Able to do all things.

(132) Unto this, then, summon (O Muhammad). And be thou upright as thou art commanded, and follow not their lusts, but say: I believe in whatever scripture Allah hath sent down, and I am commanded to be just among you. Allah is our Lord and your Lord. Unto us our works and unto you your works; no argument between us and you. Allah will bring us together, and unto Him is the journeying.

(133) And if Allah were to enlarge the provision for His slaves they would surely rebel in the earth, but He sendeth down by measure as He willeth. Lo! He is Informed, a Seer of His bondmen.

(134) And He it is Who sendeth down the saving rain after they have despaired, and spreadeth out His mercy. He is the Protecting Friend, the Praiseworthy.

(135) And Who sendeth down water from the sky in (due) measure, and We revive a dead land therewith. Even so will ye be brought forth;

(136) And the difference of night and day and the provision that Allah sendeth down from the sky and thereby quickeneth the earth after her death, and the ordering of the winds, are portents for a people who have sense.

(137) Now when ye meet in battle those who disbelieve, then it is smiting of the necks until, when ye have routed them, then making fast of bonds; and afterward either grace or ransom till the war lay down its burdens. That (is the ordinance). And if Allah willed He could have punished them (without you) but (thus it is ordained) that He may try some of you by means of others. And those who are slain in the way of Allah, He rendereth not their actions vain.

(138) He it is Who sent down peace of reassurance into the hearts of the believers that they might add faith unto their faith. Allah's are the hosts of the heavens and the earth, and Allah is ever Knower, Wise -

(139) Allah was well pleased with the believers when they swore allegiance unto thee beneath the tree, and He knew what was in their hearts, and He sent down peace of reassurance on them, and hath rewarded them with a near victory;

(140) When those who disbelieve had set up in their hearts zealotry, the zealotry of the Age of Ignorance, then Allah sent down His peace of reassurance upon His messenger and upon the believers and imposed on them the word of self-restraint, for they were worthy of it and meet for it. And Allah is Aware of all things.
