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

(11) O ye who believe! When ye contract a debt for a fixed term, record it in writing. Let a scribe record it in writing between you in (terms of) equity. No scribe should refuse to write as Allah hath taught him, so let him write, and let him who incurreth the debt dictate, and let him observe his duty to Allah his Lord, and diminish naught thereof. But if he who oweth the debt is of low understanding, or weak, or unable himself to dictate, then let the guardian of his interests dictate in (terms of) equity. And call to witness, from among your men, two witnesses. And if two men be not (at hand) then a man and two women, of such as ye approve as witnesses, so that if the one erreth (through forgetfulness) the other will remember. And the witnesses must not refuse when they are summoned. Be not averse to writing down (the contract) whether it be small or great, with (record of) the term thereof. That is more equitable in the sight of Allah and more sure for testimony, and the best way of avoiding doubt between you; save only in the case when it is actual merchandise which ye transfer among yourselves from hand to hand. In that case it is no sin for you if ye write it not. And have witnesses when ye sell one to another, and let no harm be done to scribe or witness. If ye do (harm to them) lo! it is a sin in you. Observe your duty to Allah. Allah is teaching you. And Allah is knower of all things.

(12) When thou didst say unto the believers: Is it not sufficient for you that your Lord should support you with three thousand angels sent down (to your help)?

(13) Then, after grief, He sent down security for you. As slumber did it overcome a party of you, while (the other) party, who were anxious on their own account, thought wrongly of Allah, the thought of ignorance. They said: Have we any part in the cause? Say (O Muhammad): The cause belongeth wholly to Allah. They hide within themselves (a thought) which they reveal not unto thee, saying: Had we had any part in the cause we should not have been slain here. Say: Even though ye had been in your houses, those appointed to be slain would have gone forth to the places where they were to lie. (All this hath been) in order that Allah might try what is in your breasts and prove what is in your hearts. Allah is Aware of what is hidden in the breasts (of men).

(14) And if We had decreed for them: Lay down your lives or go forth from your dwellings, but few of them would have done it; though if they did what they are exhorted to do it would be better for them, and more strengthening;

(15) Hast thou not seen those unto whom it was said: Withhold your hands, establish worship and pay the poordue, but when fighting was prescribed for them behold! a party of them fear mankind even as their fear of Allah or with greater fear, and say: Our Lord! Why hast Thou ordained fighting for us? If only Thou wouldst give us respite yet a while! Say (unto them, O Muhammad): The comfort of this world is scant; the Hereafter will be better for him who wardeth off (evil); and ye will not be wronged the down upon a date-stone.

(16) O mankind! Now hath a proof from your Lord come unto you, and We have sent down unto you a clear light;

(17) Your guardian can be only Allah; and His messenger and those who believe, who establish worship and pay the poordue, and bow down (in prayer).

(18) When the disciples said: O Jesus, son of Mary! Is thy Lord able to send down for us a table spread with food from heaven? He said: Observe your duty to Allah, if ye are true believers.

(19) Jesus, son of Mary, said: O Allah, Lord of us! Send down for us a table spread with food from heaven, that it may be a feast for us, for the first of us and for the last of us, and a sign from Thee. Give us sustenance, for Thou art the Best of Sustainers.

(20) Allah said: Lo! I send it down for you. And whoso disbelieveth of you afterward, him surely will I punish with a punishment wherewith I have not punished any of (My) creatures.
