The word(s) "betray" appears 10 time(s) in 7 verse(s) in Quran in Saheeh International translation.

(1) It is not [attributable] to any prophet that he would act unfaithfully [in regard to war booty]. And whoever betrays, [taking unlawfully], will come with what he took on the Day of Resurrection. Then will every soul be [fully] compensated for what it earned, and they will not be wronged.

(2) O you who have believed, do not betray Allah and the Messenger or betray your trusts while you know [the consequence].

(3) If you [have reason to] fear from a people betrayal, throw [their treaty] back to them, [putting you] on equal terms. Indeed, Allah does not like traitors.

(4) But if they intend to betray you - then they have already betrayed Allah before, and He empowered [you] over them. And Allah is Knowing and Wise.

(5) That is so al-'Azeez will know that I did not betray him in [his] absence and that Allah does not guide the plan of betrayers.

(6) And Satan will say when the matter has been concluded, "Indeed, Allah had promised you the promise of truth. And I promised you, but I betrayed you. But I had no authority over you except that I invited you, and you responded to me. So do not blame me; but blame yourselves. I cannot be called to your aid, nor can you be called to my aid. Indeed, I deny your association of me [with Allah] before. Indeed, for the wrongdoers is a painful punishment."

(7) Allah presents an example of those who disbelieved: the wife of Noah and the wife of Lot. They were under two of Our righteous servants but betrayed them, so those prophets did not avail them from Allah at all, and it was said, "Enter the Fire with those who enter."
