The word(s) "additional" appears 3 time(s) in 3 verse(s) in Quran in Saheeh International translation.

(1) And from [part of] the night, pray with it as additional [worship] for you; it is expected that your Lord will resurrect you to a praised station.

(2) Not lawful to you, [O Muhammad], are [any additional] women after [this], nor [is it] for you to exchange them for [other] wives, even if their beauty were to please you, except what your right hand possesses. And ever is Allah, over all things, an Observer.

(3) And Allah created you from dust, then from a sperm-drop; then He made you mates. And no female conceives nor does she give birth except with His knowledge. And no aged person is granted [additional] life nor is his lifespan lessened but that it is in a register. Indeed, that for Allah is easy.
