The word(s) "rain" appears 104 time(s) in 88 verse(s) in Quran in Mohsin Khan translation.

(61) Verily Allah, with Him (Alone) is the knowledge of the Hour, He sends down the rain, and knows that which is in the wombs. No person knows what he will earn tomorrow, and no person knows in what land he will die. Verily, Allah is All-Knower, All-Aware (of things).

(62) O mankind! Remember the Grace of Allah upon you! Is there any creator other than Allah who provides for you from the sky (rain) and the earth? La ilaha illa Huwa (none has the right to be worshipped but He). How then are you turning away (from Him)?

(63) See you not that Allah sends down water (rain) from the sky, and We produce therewith fruits of various colours, and among the mountains are streaks white and red, of varying colours and (others) very black.

(64) And a sign for them is the dead land. We give it life, and We bring forth from it grains, so that they eat thereof.

(65) And beside them will be Qasirat-at-Tarf [chaste females (wives), restraining their glances (desiring none except their husbands)], with wide and beautiful eyes.

(66) When there were displayed before him, in the afternoon, well trained horses of the highest breed [for Jihad (holy fighting in Allah's Cause)].

(67) And beside them will be Qasirat-at-Tarf [chaste females (wives) restraining their glances (desiring none except their husbands)], (and) of equal ages.

(68) See you not that Allah sends down water (rain) from the sky, and causes it to penetrate the earth, (and then makes it to spring up) as water-springs, and afterward thereby produces crops of different colours, and afterward they wither and you see them turn yellow; then He makes them dry and broken pieces. Verily, in this is a Reminder for men of understanding.

(69) It is He Who shows you His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and sends down (rain with which grows) provision for you from the sky. And none remembers but those who turn (to Allah in obedience and) in repentance (by begging His Pardon and by worshipping and obeying Him Alone and none else).

(70) And among His Signs (in this), that you see the earth barren; but when We send down water (rain) to it, it is stirred to life and growth (of vegetations). Verily, He Who gives it life, surely, is Able to give life to the dead (on the Day of Resurrection). Indeed He is Able to do all things.
