The word(s) "periods-" appears 1 time(s) in 1 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And He it is Who created the heavens and the earth in six periods-- and His dominion (extends) on the water-- that He might manifest to you, which of you is best in action, and if you say, surely you shall be raised up after death, those who disbelieve would certainly say: This is nothing but clear magic.
