The word(s) "rain" appears 100 time(s) in 96 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) And We refrain from sending the signs, only because the men of former generations treated them as false: We sent the she-camel to the Thamud to open their eyes, but they treated her wrongfully: We only send the Signs by way of terror (and warning from evil).

(52) Set forth to them the similitude of the life of this world: It is like the rain which we send down from the skies: the earth's vegetation absorbs it, but soon it becomes dry stubble, which the winds do scatter: it is (only) Allah who prevails over all things.

(53) Nor strain thine eyes in longing for the things We have given for enjoyment to parties of them, the splendour of the life of this world, through which We test them: but the provision of thy Lord is better and more enduring.

(54) Nay, We hurl the Truth against falsehood, and it knocks out its brain, and behold, falsehood doth perish! Ah! woe be to you for the (false) things ye ascribe (to Us).

(55) O mankind! if ye have a doubt about the Resurrection, (consider) that We created you out of dust, then out of sperm, then out of a leech-like clot, then out of a morsel of flesh, partly formed and partly unformed, in order that We may manifest (our power) to you; and We cause whom We will to rest in the wombs for an appointed term, then do We bring you out as babes, then (foster you) that ye may reach your age of full strength; and some of you are called to die, and some are sent back to the feeblest old age, so that they know nothing after having known (much), and (further), thou seest the earth barren and lifeless, but when We pour down rain on it, it is stirred (to life), it swells, and it puts forth every kind of beautiful growth (in pairs).

(56) Seest thou not that Allah sends down rain from the sky, and forthwith the earth becomes clothed with green? for Allah is He Who understands the finest mysteries, and is well-acquainted (with them).

(57) Seest thou not that Allah has made subject to you (men) all that is on the earth, and the ships that sail through the sea by His Command? He withholds the sky (rain) from falling on the earth except by His leave: for Allah is Most Kind and Most Merciful to man.

(58) And We send down water from the sky according to (due) measure, and We cause it to soak in the soil; and We certainly are able to drain it off (with ease).

(59) Seest thou not that Allah makes the clouds move gently, then joins them together, then makes them into a heap? - then wilt thou see rain issue forth from their midst. And He sends down from the sky mountain masses (of clouds) wherein is hail: He strikes therewith whom He pleases and He turns it away from whom He pleases, the vivid flash of His lightning well-nigh blinds the sight.

(60) And the (Unbelievers) must indeed have passed by the town on which was rained a shower of evil: did they not then see it (with their own eyes)? But they fear not the Resurrection.
