Quran 33:15 — Surah Al-Ahzab, ayah 15

وَلَقَدۡ كَانُواْ عَٰهَدُواْ ٱللَّهَ مِن قَبۡلُ لَا يُوَلُّونَ ٱلۡأَدۡبَٰرَۚ وَكَانَ عَهۡدُ ٱللَّهِ مَسۡـُٔولٗا

And they had already promised Allah before not to turn their backs and flee. And ever is the promise to Allah [that about which one will be] questioned

a bili su se još prije Allahu obavezali da neće uzmicati – a za Allahu datu obavezu će se odgovarati!
