The word(s) "day" appears 568 time(s) in 513 verse(s) in Quran in Muhammad Pickthal translation.

(331) The Exalter of Ranks, the Lord of the Throne. He causeth the Spirit of His command upon whom He will of His slaves, that He may warn of the day of Meeting,

(332) The day when they come forth, nothing of them being hidden from Allah. Whose is the Sovereignty this day? It is Allah's, the One, the Almighty.

(333) This day is each soul requited that which it hath earned; no wrong (is done) this day. Lo! Allah is swift at reckoning.

(334) Warn them (O Muhammad) of the day of the approaching (doom), when the hearts will be choking the throats, (when) there will be no friend for the wrong-doers, nor any intercessor who will be heard.

(335) Moses said: Lo! I seek refuge in my Lord and your Lord from every scorner who believeth not in a day of Reckoning.

(336) O my people! Yours is the kingdom to-day, ye being uppermost in the land. But who would save us from the wrath of Allah should it reach us? Pharaoh said: I do but show you what I think, and I do but guide you to wise policy.

(337) And, O my people! Lo! I fear for you a day of Summoning,

(338) A day when ye will turn to flee, having no preserver from Allah: and he whom Allah sendeth astray, for him there is no guide.

(339) The Fire; they are exposed to it morning and evening; and on the day when the Hour upriseth (it is said): Cause Pharaoh's folk to enter the most awful doom.

(340) And those in the Fire say unto the guards of hell: Entreat your Lord that He relieve us of a day of the torment.
