(And verily they had already sworn unto Allah) before the battle of the Ditch, on the occasion of the battle of the Clans (that they would not turn their backs) fleeing from the idolaters. (An oath to Allah) the one who breaks his oath to Allah (must he answered for) will be asked about it on the Day of Judgement.
- 33:1515
وَلَقَدْ كَانُوا عَاهَدُوا اللَّهَ مِنْ قَبْلُ لَا يُوَلُّونَ الْأَدْبَارَ ۚ وَكَانَ عَهْدُ اللَّهِ مَسْئُولًا
And indeed they had already made a covenant with Allah not to turn their backs, and a covenant with Allah must be answered for.
