[Pooya/Ali Commentary 3:140] As stated in the commentary of verses 121 and 122 of this surah due to the fearless overpowering valour of Ali the enemy suffered heavy losses in men and material and finally ran away from the scene of combat, inflicted with a humiliating defeat. The setback the Muslims encountered (due to their greed and lack of discipline) can be described as the vicissitudes of success and failure. Allah intended, by this reverse, to sift the true from the false among those who professed Islam. He wanted to test those who came into the fold of Islam for material gain, pride and glory of victories. They failed miserably. Running away from the battlefield by deserting the Holy Prophet was a shameful deed, as stated in verse 135 of this surah, exposing their inherent falsehood. The early converts, more often than not, due to weakness in their faith, availed every opportunity to save their skin in the time of trouble. They were infidels at heart in the garb of hypocrisy. They were the hidden enemies of the Holy Prophet and his Ahl ul Bayt. On the other hand there was Ali, the representative of the Ahl ul Bayt in the battle of Uhad, who not only stood by the Holy Prophet and protected him from the assassins but also turned the sure defeat into victory by dispersing the enemy through his steadfastness. This verse guides mankind, in all ages, to identify the sincere supporter of the Holy Prophet and his mission, and to distinctly name those deserters and hypocrites who have been described as the unjust (zalimin), whose names have been written in all the authentic books of history compiled by the well-known authors. Allah does not love the unjust. Mere companionship of the Holy Prophet is not enough to be blessed. Those who claim "striving hard" must undergo hard test.
