The word(s) "days" appears 27 time(s) in 23 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) What do they wait for then but the like of the days of those who passed away before them? Say: Wait then; surely I too am with you of those who wait.

(12) But they slew her, so he said: Enjoy yourselves in your abode for three days, that is a promise not to be belied.

(13) And certainly We sent Musa with Our communications, saying: Bring forth your people from utter darkness into light and remind them of the days of Allah; most surely there are signs in this for every patient, grateful one.

(14) Say: As for him who remains in error, the Beneficent Allah will surely prolong his length of days, until they see what they were threatened with, either the punishment or the hour; then they shall know who is in more evil plight and weaker in forces

(15) Therefore be not in haste against them, We only number out to them a number (of days).

(16) That they may witness advantages for them and mention the name of Allah during stated days over what He has given them of the cattle quadrupeds, then eat of them and feed the distressed one, the needy.

(17) And We made between them and the towns which We had blessed (other) towns to be easily seen, and We apportioned the journey therein: Travel through them nights and days, secure.

(18) So We sent on them a furious wind in unlucky days, that We may make them taste the chastisement of abasement in this world's life; and certainly the chastisement of the hereafter is much more abasing, and they shall not be helped.

(19) Say to those who believe (that) they forgive those who do not fear the days of Allah that He may reward a people for what they earn.

(20) When those who disbelieved harbored in their hearts (feelings of) disdain, the disdain of (the days of) ignorance, but Allah sent down His tranquillity on His Apostle and on the believers, and made them keep the word of guarding (against evil), and they were entitled to it and worthy of it; and Allah is Cognizant of all things.
