The word(s) "chosen" appears 24 time(s) in 23 verse(s) in Quran in Mohsin Khan translation.

(11) "And I have chosen you, for Myself.

(12) And strive hard in Allah's Cause as you ought to strive (with sincerity and with all your efforts that His Name should be superior). He has chosen you (to convey His Message of Islamic Monotheism to mankind by inviting them to His religion of Islam), and has not laid upon you in religion any hardship: it is the religion of your father Ibrahim (Abraham) (Islamic Monotheism). It is He (Allah) Who has named you Muslims both before and in this (the Qur'an), that the Messenger (Muhammad صلى الله عليه وسلم) may be a witness over you and you be witnesses over mankind! So perform As-Salat (Iqamat-as-Salat), give Zakat and hold fast to Allah [i.e. have confidence in Allah, and depend upon Him in all your affairs]. He is your Maula (Patron, Lord), what an Excellent Maula (Patron, Lord) and what an Excellent Helper!

(13) Allah has promised those among you who believe and do righteous good deeds, that He will certainly grant them succession to (the present rulers) in the land, as He granted it to those before them, and that He will grant them the authority to practise their religion which He has chosen for them (i.e. Islam). And He will surely give them in exchange a safe security after their fear (provided) they (believers) worship Me and do not associate anything (in worship) with Me. But whoever disbelieves after this, they are the Fasiqun (rebellious, disobedient to Allah).

(14) Say (O Muhammad صلى الله عليه وسلم): "Praise and thanks be to Allah, and peace be on His slaves whom He has chosen (for His Message)! Is Allah better, or (all) that you ascribe as partners (to Him)?" (Of course, Allah is Better).

(15) Save the chosen slaves of Allah (i.e. the true believers of Islamic Monotheism).

(16) Except the chosen slaves of Allah (faithful, obedient, and true believers of Islamic Monotheism).

(17) Except the chosen slaves of Allah.

(18) Has He (then) chosen daughters rather than sons?

(19) "We would have indeed been the chosen slaves of Allah (true believers of Islamic Monotheism)!"

(20) And they are with Us, verily, of the chosen and the best!
