The word(s) "folk" appears 309 time(s) in 289 verse(s) in Quran in Muhammad Pickthal translation.

(221) And We left for him among the later folk (the salutation):

(222) And We left for them among the later folk (the salutation):

(223) When he said unto his folk: Will ye not ward off (evil)?

(224) And we left for him among the later folk (the salutation):

(225) And We sent him to a hundred thousand (folk) or more

(226) The folk of Noah before them denied (their messenger) and (so did the tribe of) A'ad, and Pharaoh firmly planted,

(227) And (the tribe of) Thamud, and the folk of Lot, and the dwellers in the wood: these were the factions.

(228) Then worship what ye will beside Him. Say: The losers will be those who lose themselves and their housefolk on the Day of Resurrection. Ah, that will be the manifest loss!

(229) The folk of Noah and the factions after them denied (their messengers) before these, and every nation purposed to seize their messenger and argued falsely, (thinking) thereby to refute the Truth. Then I seized them, and how (awful) was My punishment.

(230) A plight like that of Noah's folk, and A'ad and Thamud, and those after them, and Allah willeth no injustice for (His) slaves.
