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

(11) Yet of mankind are some who take unto themselves (objects of worship which they set as) rivals to Allah, loving them with a love like (that which is the due) of Allah (only) - those who believe are stauncher in their love for Allah - Oh, that those who do evil had but known, (on the day) when they behold the doom, that power belongeth wholly to Allah, and that Allah is severe in punishment!

(12) (On the day) when those who were followed disown those who followed (them), and they behold the doom, and all their aims collapse with them.

(13) Lo! those who hide aught of the Scripture which Allah hath revealed and purchase a small gain therewith, they eat into their bellies nothing else than fire. Allah will not speak to them on the day of Resurrection, nor will He make them grow. Theirs will be a painful doom.

(14) It is not righteousness that ye turn your faces to the East and the West; but righteous is he who believeth in Allah and the Last day and the angels and the Scripture and the prophets; and giveth wealth, for love of Him, to kinsfolk and to orphans and the needy and the wayfarer and to those who ask, and to set slaves free; and observeth proper worship and payeth the poor-due. And those who keep their treaty when they make one, and the patient in tribulation and adversity and time of stress. Such are they who are sincere. Such are the Allah-fearing.

(15) (Fast) a certain number of days; and (for) him who is sick among you, or on a journey, (the same) number of other days; and for those who can afford it there is a ransom: the feeding of a man in need - but whoso doeth good of his own accord, it is better for him: and that ye fast is better for you if ye did but know -

(16) The month of Ramadan in which was revealed the Qur'an, a guidance for mankind, and clear proofs of the guidance, and the Criterion (of right and wrong). And whosoever of you is present, let him fast the month, and whosoever of you is sick or on a journey, (let him fast the same) number of other days. Allah desireth for you ease; He desireth not hardship for you; and (He desireth) that ye should complete the period, and that ye should magnify Allah for having guided you, and that peradventure ye may be thankful.

(17) Perform the pilgrimage and the visit (to Makka) for Allah. And if ye are prevented, then send such gifts as can be obtained with ease, and shave not your heads until the gifts have reached their destination. And whoever among you is sick or hath an ailment of the head must pay a ransom of fasting or almsgiving or offering. And if ye are in safety, then whosoever contenteth himself with the visit for the pilgrimage (shall give) such gifts as can be had with ease. And whosoever cannot find (such gifts), then a fast of three days while on the pilgrimage, and of seven when ye have returned; that is, ten in all. That is for him whoso folk are not present at the Inviolable Place of Worship. Observe your duty to Allah, and know that Allah is severe in punishment.

(18) Remember Allah through the appointed days. Then whoso hasteneth (his departure) by two days, it is no sin for him, and whoso delayeth, it is no sin for him; that is for him who wardeth off (evil). Be careful of your duty to Allah, and know that unto Him ye will be gathered.

(19) Beautified is the life of the world for those who disbelieve; they make a jest of the believers. But those who keep their duty to Allah will be above them on the day of Resurrection. Allah giveth without stint to whom He will.

(20) Your women are a tilth for you (to cultivate) so go to your tilth as ye will, and send (good deeds) before you for your souls, and fear Allah, and know that ye will (one day) meet Him. Give glad tidings to believers, (O Muhammad).
