The word(s) "drown" appears 26 time(s) in 26 verse(s) in Quran in Mohsin Khan translation.

(11) So they both proceeded, till, when they embarked the ship, he (Khidr) scuttled it. Musa (Moses) said: "Have you scuttled it in order to drown its people? Verily, you have committed a thing "Imr" (a Munkar - evil, bad, dreadful thing)."

(12) And indeed We revealed to Musa (Moses) (saying): "Travel by night with Ibadi (My slaves) and strike a dry path for them in the sea, fearing neither to be overtaken [by Fir'aun (Pharaoh)] nor being afraid (of drowning in the sea)."

(13) We helped him against the people who denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.). Verily, they were a people given to evil. So We drowned them all.

(14) So We revealed to him (saying): "Construct the ship under Our Eyes and under Our Revelation (guidance). Then, when Our Command comes, and water gushes forth from the oven, take on board of each kind two (male and female), and your family, except those thereof against whom the Word has already gone forth. And address Me not in favour of those who have done wrong. Verily, they are to be drowned.

(15) Verily, in this [what We did as regards drowning of the people of Nuh (Noah)], there are indeed Ayat (proofs, evidence, lessons, signs, etc. for men to understand), for sure We are ever putting (men) to the test.

(16) And Nuh's (Noah) people, when they denied the Messengers, We drowned them, and We made them as a sign for mankind. And We have prepared a painful torment for the Zalimun (polytheists and wrong-doers).

(17) Then We drowned the others.

(18) Then We drowned the rest (disbelievers) thereafter.

(19) So We seized him and his hosts, and We threw them all into the sea (and drowned them). So behold (O Muhammad صلى الله عليه وسلم) what was the end of the Zalimun [wrong-doers, polytheists and those who disbelieved in the Oneness of their Lord (Allah), or rejected the advice of His Messenger Musa (Moses) عليه السلام].

(20) So We punished each (of them) for his sins; of them were some on whom We sent Hasib (a violent wind with shower of stones) [as on the people of Lut (Lot)], and of them were some who were overtaken by As-Saihah [torment - awful cry. (as Thamud or Shu'aib's people)], and of them were some whom We caused the earth to swallow [as Qarun (Korah)], and of them were some whom We drowned [as the people of Nuh (Noah), or Fir'aun (Pharaoh) and his people]. It was not Allah Who wronged them, but they wronged themselves.
