The word(s) "befalls" appears 16 time(s) in 15 verse(s) in Quran in Mohsin Khan translation.

(11) 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!

(12) And everything, small and big, is written down (in Al-Lauh Al-Mahfuz already beforehand i.e. before it befalls, or is done by its doer: الإيمان بالقدر) (See the Qur'an V.57:22 and its footnote).

(13) When the Event (i.e. the Day of Resurrection) befalls.

(14) No calamity befalls on the earth or in yourselves but it is inscribed in the Book of Decrees (Al-Lauh Al-Mahfuz) before We bring it into existence. Verily, that is easy for Allah.

(15) No calamity befalls, but by the Leave [i.e. Decision and Qadar (Divine Preordainments)] of Allah, and whosoever believes in Allah, He guides his heart [to the true Faith with certainty, i.e. what has befallen him was already written for him by Allah from the Qadar (Divine Preordainments)]. And Allah is the All-Knower of everything.
