The word(s) "rain" appears 67 time(s) in 58 verse(s) in Quran in Muhammad Pickthal translation.

(41) Lo! Allah! With Him is knowledge of the Hour. He sendeth down the rain, and knoweth that which is in the wombs. No soul knoweth what it will earn to-morrow, and no soul knoweth in what land it will die. Lo! Allah is Knower, Aware.

(42) A token unto them is the dead earth. We revive it, and We bring forth from it grain so that they eat thereof;

(43) He hath created the heavens and the earth with truth. He maketh night to succeed day, and He maketh day to succeed night, and He constraineth the sun and the moon to give service, each running on for an appointed term. Is not He the Mighty, the Forgiver?

(44) And verily, if thou shouldst ask them: Who created the heavens and the earth? they will say: Allah. Say: Bethink you then of those ye worship beside Allah, if Allah willed some hurt for me, could they remove from me His hurt; or if He willed some mercy for me, could they restrain His mercy? Say: Allah is my all. In Him do (all) the trusting put their trust.

(45) 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.

(46) Then, when they beheld it as a dense cloud coming toward their valleys, they said: Here is a cloud bringing us rain. Nay, but it is that which ye did seek to hasten, a wind wherein is painful torment,

(47) 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.

(48) And We send down from the sky blessed water whereby We give growth unto gardens and the grain of crops,

(49) And those that bear the burden (of the rain)

(50) Husked grain and scented herb.
