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

(1) Yet there are men who take (for worship) others besides Allah, as equal (with Allah): They love them as they should love Allah. But those of Faith are overflowing in their love for Allah. If only the unrighteous could see, behold, they would see the penalty: that to Allah belongs all power, and Allah will strongly enforce the penalty.

(2) "This is because of the (unrighteous deeds) which your hands sent on before ye: For Allah never harms those who serve Him."

(3) He said: "O Noah! He is not of thy family: For his conduct is unrighteous. So ask not of Me that of which thou hast no knowledge! I give thee counsel, lest thou act like the ignorant!"
