The Holy Quran 8:27 — Surah Al-Anfal
Arabic text
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَخُونُوا۟ ٱللَّهَ وَٱلرَّسُولَ وَتَخُونُوٓا۟ أَمَـٰنَـٰتِكُمْ وَأَنتُمْ تَعْلَمُونَ
Translation
O you who have Imaan! Do not betray (disobey) Allaah and the Rasool ﷺ and do not knowingly betray your mutual trusts (by revealing each other's secrets, breaking promises, etc.).
Tafsir (excerpt) — Tafsir Usmani
The prohibition of betraying trusts: betraying Allah and the Messenger ﷺ means going against their commands: calling oneself a Muslim with the tongue while doing the deeds of the kafirs; or practising deceit in a task that Allah and the Messenger ﷺ have assigned; or stealing from the spoils of war, and the like.
