The word(s) "sun" appears 112 time(s) in 94 verse(s) in Quran in Mohsin Khan translation.

(21) (Remember) when Yusuf (Joseph) said to his father: "O my father! Verily, I saw (in a dream) eleven stars and the sun and the moon - I saw them prostrating themselves to me."

(22) He said: "No food will come to you (in wakefulness or in dream) as your provision, but I will inform (in wakefulness) its interpretation before it (the food) comes. This is of that which my Lord has taught me. Verily, I have abandoned the religion of a people that believe not in Allah and are disbelievers in the Hereafter (i.e. the Kan'anyyun of Egypt who were polytheists and used to worship sun and other false deities).

(23) Allah is He Who raised the heavens without any pillars that you can see. Then, He rose above (Istawa) the Throne (really in a manner that suits His Majesty). He has subjected the sun and the moon (to continue going round), each running (its course) for a term appointed. He manages and regulates all affairs; He explains the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) in detail, that you may believe with certainty in the meeting with your Lord.

(24) And if there had been a Qur'an with which mountains could be moved (from their places), or the earth could be cloven asunder, or the dead could be made to speak (it would not have been other than this Qur'an). But the decision of all things is certainly with Allah. Have not then those who believed yet known that had Allah willed, He could have guided all mankind? And a disaster will not cease to strike those who disbelieved because of their (evil) deeds or it (i.e. the disaster) settles close to their homes, until the Promise of Allah comes to pass. Certainly, Allah breaks not His Promise.

(25) And He has made the sun and the moon, both constantly pursuing their courses, to be of service to you; and He has made the night and the day, to be of service to you.

(26) So As-Saihah (torment - awful cry) overtook them at the time of sunrise.

(27) And He has subjected to you the night and the day, and the sun and the moon; and the stars are subjected by His Command. Surely, in this are proofs for people who understand.

(28) Verily, Allah enjoins Al-'Adl (i.e. justice and worshipping none but Allah Alone - Islamic Monotheism) and Al-Ihsan [i.e. to be patient in performing your duties to Allah, totally for Allah's sake and in accordance with the sunnah (legal ways) of the Prophet صلى الله عليه وسلم in a perfect manner], and giving (help) to kith and kin (i.e. all that Allah has ordered you to give them e.g., wealth, visiting, looking after them, or any other kind of help), and forbids Al-Fahsha' (i.e all evil deeds, e.g. illegal sexual acts, disobedience of parents, polytheism, to tell lies, to give false witness, to kill a life without right), and Al-Munkar (i.e all that is prohibited by Islamic law: polytheism of every kind, disbelief and every kind of evil deeds), and Al-Baghy (i.e. all kinds of oppression). He admonishes you, that you may take heed.

(29) (This was Our) sunnah (rule or way) with the Messengers We sent before you (O Muhammad صلى الله عليه و سلم), and you will not find any alteration in Our sunnah (rule or way).

(30) And you might have seen the sun, when it rose, declining to the right from their Cave, and when it set, turning away from them to the left, while they lay in the midst of the Cave. That is (one) of the Ayat (proofs, evidence, signs) of Allah. He whom Allah guides, he is the rightly guided; but he whom He sends astray, for him you will find no Wali (guiding friend) to lead him (to the right Path).
