The word(s) "performing" appears 13 time(s) in 13 verse(s) in Quran in Mohsin Khan translation.

(11) Giving glad tidings [of Paradise to the one who believes in the Oneness of Allah (i.e. Islamic Monotheism) and fears Allah much (abstains from all kinds of sins and evil deeds) and loves Allah much (performing all kinds of good deeds which He has ordained)], and warning (of punishment in the Hell-Fire to the one who disbelieves in the Oneness of Allah), but most of them turn away, so they hear not.

(12) So unto this (religion of Islam alone and this Qur'an) then invite (people) (O Muhammad صلى الله عليه و سلم), and stand firm [on Islamic Monotheism by performing all that is ordained by Allah (good deeds), and by abstaining from all that is forbidden by Allah (sins and evil deeds)], as you are commanded, and follow not their desires but say: "I believe in whatsoever Allah has sent down of the Book [all the holy Books, - this Qur'an and the Books of the old from the Taurat (Torah), or the Injeel (Gospel) or the Pages of Ibrahim (Abraham)] and I am commanded to do justice among you. Allah is our Lord and your Lord. For us our deeds and for you your deeds. There is no dispute between us and you. Allah will assemble us (all), and to Him is the final return."

(13) And those foremost [(in Islamic Faith of Monotheism and in performing righteous deeds) in the life of this world on the very first call for to embrace Islam] will be foremost (in Paradise).
