The word(s) "upon" appears 287 time(s) in 260 verse(s) in Quran in Muhammad Habib Shakir translation.

(191) And should you ask them, Who created the heavens and the earth? They would most certainly say: Allah. Say: Have you then considered that what you call upon besides Allah, would they, if Allah desire to afflict me with harm, be the removers of His harm, or (would they), if Allah desire to show me mercy, be the withholders of His mercy? Say: Allah is sufficient for me; on Him do the reliant rely.

(192) So when harm afflicts a man he calls upon Us; then, when We give him a favor from Us, he says: I have been given it only by means of knowledge. Nay, it is a trial, but most of them do not know.

(193) Surely those who disbelieve shall be cried out to: Certainly Allah's hatred (of you) when you were called upon to the faith and you rejected, is much greater than your hatred of yourselves.

(194) That is because when Allah alone was called upon, you disbelieved, and when associates were given to Him, you believed; so judgment belongs to Allah, the High, the Great.

(195) Therefore call upon Allah, being sincere to Him in obedience, though the unbelievers are averse:

(196) Possessor of the highest rank, Lord of power: He makes the inspiration to light by His command upon whom He pleases of His servants, that he may warn (men) of the day of meeting.

(197) And Allah judges with the truth; and those whom they call upon besides Him cannot judge aught; surely Allah is the Hearing, the Seeing.

(198) And Firon said: Let me alone that I may slay Musa and let him call upon his Lord; surely I fear that he will change your religion or that he will make mischief to appear in the land.

(199) And those who are in the fire shall say to the keepers of hell: Call upon your Lord that He may lighten to us one day of the punishment.

(200) And your Lord says: Call upon Me, I will answer you; surely those who are too proud for My service shall soon enter hell abased.
