Mujahid said the meaning of «مسجور» (which is in Surah at-Tur) is "full," and others said the meaning of «سجرت‏» is that the seas will burst forth and merge together to become one sea. «خنس» means "at the place of walking, then returning." «كنس» is derived from «تكنس» , meaning "they hide like deer." «تنفس‏» means "when the day rises." «ظنين» (with ظاء mu'jamah, this is also a recitation) means "he accuses," and «ضنين» means "he is not stingy in conveying Allah's message."
