The word(s) "course" appears 48 time(s) in 46 verse(s) in Quran in Mohsin Khan translation.

(21) 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.

(22) 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.

(23) "And befool them gradually those whom you can among them with your voice (i.e. songs, music, and any other call for Allah's disobedience), make assaults on them with your cavalry and your infantry, share with them wealth and children (by tempting them to earn money by illegal ways - usury, or by committing illegal sexual intercourse), and make promises to them." But Satan promises them nothing but deceit.

(24) And he had property (or fruit) and he said to his companion, in the course of mutual talk: "I am more than you in wealth and stronger in respect of men." (Tafsir Al-Qurtubi).

(25) He said: "Do you remember when we betook ourselves to the rock? I indeed forgot the fish; none but Shaitan (Satan) made me forget to remember it. It took its course into the sea in a strange (way)!"

(26) Lord of the heavens and the earth, and all that is between them, so worship Him (Alone) and be constant and patient in His worship. Do you know of any who is similar to Him? (of course none is similar or co-equal or comparable to Him, and He has none as partner with Him). [There is nothing like Him and He is the All-Hearer, the All-Seer].

(27) Verily, those who like that (the crime of) illegal sexual intercourse should be propagated among those who believe, they will have a painful torment in this world and in the Hereafter. And Allah knows and you know not.

(28) O you who believe! Follow not the footsteps of Shaitan (Satan). And whosoever follows the footsteps of Shaitan (Satan), then, verily he commands Al-Fahsha' [i.e. to commit indecency (illegal sexual intercourse)], and Al-Munkar [disbelief and polytheism (i.e. to do evil and wicked deeds; and to speak or to do what is forbidden in Islam)]. And had it not been for the Grace of Allah and His Mercy on you, not one of you would ever have been pure from sins. But Allah purifies (guides to Islam) whom He wills, and Allah is All-Hearer, All-Knower.

(29) And those who invoke not any other ilah (god) along with Allah, nor kill such person as Allah has forbidden, except for just cause, nor commit illegal sexual intercourse - and whoever does this shall receive the punishment.

(30) And (remember) Lut (Lot)! When he said to his people. Do you commit Al-Fahishah (evil, great sin, every kind of unlawful sexual intercourse, sodomy) while you see (one another doing evil without any screen)?"
