﴿ إِذْ أَنتُم بِٱلْعُدْوَةِ ٱلدُّنْيَا وَهُم بِٱلْعُدْوَةِ ٱلْقُصْوَىٰ وَٱلرَّكْبُ أَسْفَلَ مِنكُمْ ۚ وَلَوْ تَوَاعَدتُّمْ لَٱخْتَلَفْتُمْ فِى ٱلْمِيعَٰدِ ۙ وَلَٰكِن لِّيَقْضِىَ ٱللَّهُ أَمْرًۭا كَانَ مَفْعُولًۭا لِّيَهْلِكَ مَنْ هَلَكَ عَنۢ بَيِّنَةٍۢ وَيَحْيَىٰ مَنْ حَىَّ عَنۢ بَيِّنَةٍۢ ۗ وَإِنَّ ٱللَّهَ لَسَمِيعٌ عَلِيمٌ ﴾

“[Remember that day] when you were at the near end of the valley [of Badr], and they were at its farthest end, while the caravan was below you. And if you had known that a battle was to take place, you would indeed have refused to accept the challenge: but [the battle was brought about none the less,] so that God might accomplish a thing [which He willed] to be done, [and] that he who would perish might perish in clear evidence of the truth, and that he who would remain alive might live in clear evidence of the truth. And, behold, God is indeed all-hearing, all-knowing.”

It is the intention of Almighty God that the Truth being true and falsehood being false should be absolutely clear to the people. Initially, this work is done through the call given in the language of argument. The missionary, by using powerful but easily understood arguments, proves the Truth being true and falsehood being false. The completion of this work is finally effected by extraordinary happenings. Such events take either the shape of a heavenly miracle or domination on earth. The latter event took place at the battle of Badr. The Quraysh set out from Makkah to lend their assistance to their trading caravan coming in from Syria. The Muslims set out from Madinah to attack this caravan, but it deviated from the usual path, going along the seacoast, and thus escaped being attacked. The two parties then reached Badr and confronted each other. This happened at the behest of God. Both the parties were made to clash with each other and the victory was awarded to the people of the Faith. In this way, the veracity of the Prophet and that of his mission became abundantly clear to the people. It was finally clear to those who were true seekers of the truth that this was the real Truth while those who remained disaffected because of psychological complications persisted in their stand and thus proved that they deserved to be eliminated.
