And the Hypocrites also. These were told: "Come, fight in the way of Allah, or (at least) drive (The foe from your city)." They said: "Had we known how to fight, we should certainly have followed you." They were that day nearer to Unbelief than to Faith, saying with their lips what was not in their hearts but Allah hath full knowledge of all they conceal. Ali 'Imran 3:167 ⧉
Tafsir:
In the confrontation between truth and untruth, truth is always destined to have the final victory, because truth always has God on its side. However, this world being a world of trial, mischief-mongers too have full freedom of action. That is why at times, by exploiting some weakness of the believers—for instance, mutual dissension—they are able to inflict temporary harm on them. Yet such happenings, though tragic in appearance, have a good side to them as well, for in this way Muslims are put to the test. In the face of unfavourable situations, the insincere fall away, while the true believers persevere because of their total trust in God. In this way, it becomes clear who are the trustworthy and who are not. Furthermore, God’s mercy is all the more focussed upon them, when, after incurring loss due to their inadvertent mistakes, the believers turn to God once again in all patience and humility.
