The word(s) "sun" appears 64 time(s) in 61 verse(s) in Quran in Abdullah Yusuf Ali translation.

(41) He created the heavens and the earth in true (proportions): He makes the Night overlap the Day, and the Day overlap the Night: He has subjected the sun and the moon (to His law): Each one follows a course for a time appointed. Is not He the Exalted in Power - He Who forgives again and again?

(42) Among His Signs are the Night and the Day, and the sun and the Moon. Do not prostrate to the sun and the moon, but prostrate to Allah, Who created them, if it is Him ye wish to serve.

(44) Bear, then, with patience, all that they say, and celebrate the praises of thy Lord, before the rising of the sun and before (its) setting.

(45) The Day when the Earth will be rent asunder, from (men) hurrying out: that will be a gathering together,- quite easy for Us.

(46) The Hour (of Judgment) is nigh, and the moon is cleft asunder.

(47) The sun and the moon follow courses (exactly) computed;

(48) When the sky is rent asunder, and it becomes red like ointment:

(49) Had We sent down this Qur'an on a mountain, verily, thou wouldst have seen it humble itself and cleave asunder for fear of Allah. Such are the similitudes which We propound to men, that they may reflect.

(50) And the sky will be rent asunder, for it will that Day be flimsy,
