The word(s) "al-fawahish" appears 4 time(s) in 4 verse(s) in Quran in Mohsin Khan translation.

(1) Say (O Muhammad صلى الله عليه وسلم): "Come, I will recite what your Lord has prohibited you from: Join not anything in worship with Him; be good and dutiful to your parents; kill not your children because of poverty - We provide sustenance for you and for them; come not near to al-fawahish (shameful sins, illegal sexual intercourse) whether committed openly or secretly; and kill not anyone whom Allah has forbidden, except for a just cause (according to Islamic law). This He has commanded you that you may understand.

(2) Say (O Muhammad صلى الله عليه وسلم): "(But) the things that my Lord has indeed forbidden are al-fawahish (great evil sins and every kind of unlawful sexual intercourse) whether committed openly or secretly, sins (of all kinds), unrighteous oppression, joining partners (in worship) with Allah for which He has given no authority, and saying things about Allah of which you have no knowledge."

(3) And those who avoid the greater sins, and al-fawahish (illegal sexual intercourse), and when they are angry, forgive.

(4) Those who avoid great sins (See the Qur'an, Verses: 6:152,153) and al-fawahish (illegal sexual intercourse) except the small faults, - verily, your Lord is of Vast Forgiveness. He knows you well when He created you from the earth (Adam), and when you were fetuses in your mothers' wombs. So ascribe not purity to yourselves. He knows best him who fears Allah and keeps his duty to Him [i.e. those who are Al-Muttaqun (the pious. See V.2:2)].
