[2:89] When there came to them a Book from God, confirming what was with them - and they formerly prayed for victory over the disbelievers; but when there came to them what they recognized, they disbelieved in it; and the curse of God is on the disbelievers.
The allusion in it is to one who resolves upon purity and clarity (ṣafāÌ), and promises his complete loyalty (wafāÌ). He raises the banners of vigor in stepping out to combat, but when the call comes to line up and advance boldly into battle he breaks down at the rallying of the ranks and cuts himself off from the group, afraid of dangerous attacks. God Most High said: Then, when the matter has been resolved upon if they are loyal to God, it will be better for them [47:21].
