279. Commandment to approach not foul deeds, whether open or secret
[6:152] Say, ‘Come, I will rehearse to you what your Lord has forbidden: that you associate not anything as partner with Him and that you do good to parents, and that you kill not your children for fear of poverty — it is We Who provide for you and for them — and that you approach not foul deeds, whether open or secret; and that you kill not the life which Allah has made sacred, save by right. That is what He has enjoined upon you, that you may understand.
[7:29] And when they commit a foul deed, they say: ‘We found our fathers doing it, and Allah has enjoined it upon us.’ Say, ‘Allah never enjoins foul deeds. Do you say of Allah what you know not?’
[16:91] Verily, Allah enjoins justice, and the doing of good to others; and giving like kindred; and forbids indecency, and manifest evil, and wrongful transgression. He admonished you that you may take heed
[7:34] Say, ‘My Lord has only forbidden foul deeds, whether open or secret, and sin and wrongful transgression, and that you associate with Allah that for which He has sent down no authority, and that you say of Allah that of which you have no knowledge.’
[24:20] Those who love that immorality should spread among the believers, will have a painful punishment in this world and the Hereafter. And Allah knows, and you know not.
[4:149] Allah likes not the uttering of unseemly speech in public, except on the part of one who is being wronged. Verily, Allah is All-Hearing, All-Knowing.
