The word(s) "defy" appears 3 time(s) in 3 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Already has He sent you Word in the Book, that when ye hear the signs of Allah held in defiance and ridicule, ye are not to sit with them unless they turn to a different theme: if ye did, ye would be like them. For Allah will collect the hypocrites and those who defy faith - all in Hell:-

(2) The blame is only against those who oppress men and wrong-doing and insolently transgress beyond bounds through the land, defying right and justice: for such there will be a penalty grievous.

(3) Or do they intend a plot (against thee)? But those who defy Allah are themselves involved in a Plot!
