15وَلَقَد كانوا عاهَدُوا اللَّهَ مِن قَبلُ لا يُوَلّونَ الأَدبارَ ۚ وَكانَ عَهدُ اللَّهِ مَسئولًا(Muntakhab)Yet they had already given their solemn promise to Allah never to defect, desert or flee the enemy. They failed to realize that an engagement entered into with Allah is indeed an immense responsibility.
