Ibn Abbas said“When the verse“If there are twenty amongst you patient and persevering, they will vanquish two hundred”was revealed. It was heavy and troublesome for Muslims when Allaah prescribed for them that one (fighting Muslim) should not fly from ten (fighting Non-Muslims). Then a light commandment was revealed saying“For the present Allaah hath lightened your (task). ”The narrator Abu Tawbah recited the verse to“they will vanquish two hundred. ”When Allaah lightened the number, patient and perseverance also decreased according to the number lightened from them. ”

Narrated Abdullah ibn Umar: Ibn Umar was sent with a detachment of the Messenger of Allah صلی اللہ علیہ وسلم . The people wheeled round in flight. He said: I was one of those who wheeled round in flight. When we stopped, we said (i. e. thought): How should we do? We have run away from the battlefield and deserve Allah's wrath. Then we said (thought): Let us enter Madina, stay there, and go there while no one sees us. So we entered (Madina) and thought: If we present ourselves before the Messenger of Allah صلی اللہ علیہ وسلم , and if there is a change of repentance for us, we shall stay; if there is something else, we shall go away. So we sat down (waiting) for the Messenger of Allah صلی اللہ علیہ وسلم before the dawn prayer. When he came out, we stood up to him and said: We are the ones who have fled. He turned to us and said: No, you are the ones who return to fight after wheeling away. We then approached and kissed his hand, and he said; I am the main body of the Muslims.

Abu Saeed said“The verse“If any do turn his back to them on such a day”was revealed on the day of the Battle of Badr. ”
