When you have been let down by people
What the Prophet ﷺ was told to say if they turned away.
فَإِن تَوَلَّوْا۟ فَقُلْ حَسْبِىَ ٱللَّهُ لَآ إِلَـٰهَ إِلَّا هُوَ ۖ عَلَيْهِ تَوَكَّلْتُ ۖ وَهُوَ رَبُّ ٱلْعَرْشِ ٱلْعَظِيمِ
…ḥasbiya-llāhu lā ilāha illā huwa, ʿalayhi tawakkaltu wa huwa rabbu-l-ʿarshi-l-ʿaẓīm.
But if they turn away, [O Muḥammad], say, "Sufficient for me is Allāh; there is no deity except Him. On Him I have relied, and He is the Lord of the Great Throne."
