The word(s) "rejoice" appears 21 time(s) in 20 verse(s) in Quran in Mohsin Khan translation.

(11) Allah increases the provision for whom He wills, and straitens (it for whom He wills), and they rejoice in the life of the world, whereas the life of this world as compared with the Hereafter is but a brief passing enjoyment.

(12) Those to whom We have given the Book (such as 'Abdullah bin Salam and other Jews who embraced Islam), rejoice at what has been revealed unto you (i.e. the Qur'an), but there are among the Confederates (from the Jews and pagans) those who reject a part thereof. Say (O Muhammad صلى الله عليه و سلم): "I am commanded only to worship Allah (Alone) and not to join partners with Him. To Him (Alone) I call and to Him is my return."

(13) So when (the messengers with the present) came to Sulaiman (Solomon), he said: "Will you help me in wealth? What Allah has given me is better than that which He has given you! Nay, you rejoice in your gift!"

(14) Within three to nine years. The decision of the matter, before and after (these events) is only with Allah, (before the defeat of the Romans by the Persians, and after the defeat of the Persians by the Romans). And on that Day, the believers (i.e. Muslims) will rejoice (at the victory given by Allah to the Romans against the Persians) -

(15) And when We cause mankind to taste of mercy, they rejoice therein; but when some evil afflicts them because of (evil deeds and sins) that their (own) hands have sent forth, behold, they are in despair!

(16) Allah is He Who sends the winds, so that they raise clouds, and spread them along the sky as He wills, and then break them into fragments, until you see rain drops come forth from their midst! Then when He has made them fall on whom of His slaves as He wills, lo, they rejoice!

(17) And when Allah Alone is mentioned, the hearts of those who believe not in the Hereafter are filled with disgust (from the Oneness of Allah توحيد الله) and when those (whom they obey or worship) besides Him [like all false deities other than Allah, - it may be a Messenger, an angel, a pious man, a jinni, or any other creature even idols, graves of religious people, saints, priests, monks and others.] are mentioned, behold, they rejoice!

(18) That was because you had been exulting in the earth without any right (by worshipping others instead of Allah and by committing crimes), and that you used to rejoice extremely (in your error).

(19) But if they turn away (O Muhammad صلى الله عليه و سلم from the Islamic Monotheism, which you have brought to them). We have not sent you (O Muhammad صلى الله عليه و سلم) as a Hafiz (watcher, protector) over them (i.e. to take care of their deeds and to recompense them). Your duty is to convey (the Message). And verily, when We cause man to taste of Mercy from Us, he rejoices thereat; but when some ill befalls them because of the deeds which their hands have sent forth, then verily, man (becomes) ingrate!

(20) In order that you may not grieve at the things that you fail to get, nor rejoice over that which has been given to you. And Allah likes not prideful boasters.
