The word(s) "day" appears 704 time(s) in 579 verse(s) in Quran in Mohsin Khan translation.

(291) And We made them leaders inviting to the Fire: and on the day of Resurrection, they will not be helped.

(292) And We made a curse to follow them in this world, and on the day of Resurrection, they will be among Al-Maqbuhun (those who are prevented from receiving Allah's Mercy or any good; despised or destroyed).

(293) Is he whom We have promised an excellent promise (Paradise) - which he will find true - like him whom We have made to enjoy the luxuries of the life of (this) world, then on the day of Resurrection, he will be among those brought up (to be punished in the Hell-fire)?

(294) And (remember) the day when He will call to them and say: "Where are My (so-called) partners whom you used to assert?"

(295) And (remember) the day (Allah) will call to them, and say: "What answer gave you to the Messengers?"

(296) Then the news of a good answer will be obscured to them on that day, and they will not be able to ask one another.

(297) Say (O Muhammad صلى الله عليه وسلم): "Tell me! If Allah made the night continuous for you till the day of Resurrection, which ilah (god) besides Allah could bring you light? Will you not then hear?"

(298) Say (O Muhammad صلى الله عليه وسلم): "Tell me! If Allah made the day continuous for you till the day of Resurrection, which ilah (god) besides Allah could bring you night wherein you rest? Will you not then see?"

(299) It is out of His Mercy that He has made for you the night and the day that you may rest therein (i.e. during the night) and that you may seek of His Bounty (i.e. during the day) - and in order that you may be grateful.

(300) And (remember) the day when He (your Lord - Allah) will call to them (those who worshipped others along with Allah), and will say: "Where are My (so-called) partners, whom you used to assert?"
