(7) (All this happened) so that Allah may give reward to the truthful for their truthfulness, and punish the hypocrites, if He so wills, or accept their repentance. Surely, Allah is Most-Forgiving, Very-Merciful.
(7). This verse admires those companions of the Holy Prophet ﷺ who had not participated in the battle of Badr due to some valid excuses, and had vowed that whenever the next battle would come to happen, they would offer their lives in defence of faith. Then, some of them, like Sayyidna 'Anas Ibn Nadr and Mus'ab Ibn ` Umair ؓ fulfilled their vows by sacrificing their lives in the battle of 'Uhud, while some others, like Sayyidna ` Uthman and Talhah ؓ remained alive, but eagerly waiting for having the honor of being martyred in the way of Allah.
