﴿ وَلَقَدْ صَدَقَكُمُ ٱللَّهُ وَعْدَهُۥٓ إِذْ تَحُسُّونَهُم بِإِذْنِهِۦ ۖ حَتَّىٰٓ إِذَا فَشِلْتُمْ وَتَنَٰزَعْتُمْ فِى ٱلْأَمْرِ وَعَصَيْتُم مِّنۢ بَعْدِ مَآ أَرَىٰكُم مَّا تُحِبُّونَ ۚ مِنكُم مَّن يُرِيدُ ٱلدُّنْيَا وَمِنكُم مَّن يُرِيدُ ٱلْءَاخِرَةَ ۚ ثُمَّ صَرَفَكُمْ عَنْهُمْ لِيَبْتَلِيَكُمْ ۖ وَلَقَدْ عَفَا عَنكُمْ ۗ وَٱللَّهُ ذُو فَضْلٍ عَلَى ٱلْمُؤْمِنِينَ ﴾

“AND, INDEED, God made good His promise unto you when, by His leave, you were about to destroy your foes - until the moment when you lost heart and acted contrary to the [Prophet's] command, and disobeyed after He had brought you within view of that [victory] for which you were longing. There were among you such as cared for this world [alone], just as there were among you such as cared for the life to come: whereupon, in order that He might put you to a test, He prevented you from defeating your foes. But now He has effaced your sin: for God is limitless in His bounty unto the believers.”

When believers show steadfastness at crucial moments, God sends His special succour, that is, He strikes terror into the hearts of those who deny the truth. Any person or group who adheres to anything other than the true divine religion is standing in fact on quicksand. For, there is no other real base to build on in this world except the truth revealed by God. As such, whenever one has proved to be standing firmly on the ground of God’s religion, the ranks of those who deny the truth begin to show signs of disarray. Lacking sound arguments, those who deny the truth, unlike the believers, suffer from feelings of uncertainty and inferiority. This lack of conviction finally leads to their downfall. They are ultimately defeated at the hands of true believers. But in the case of the Muslims, their weakness and defeat are traceable solely to their disunity arising from dissension. Yet unity cannot come about in a society solely on the basis of uniformity of opinion. It takes united action also, even in the face of divisive opinions, to ensure total cohesiveness within a community. Only when a community thinks on this level can it remain united and powerful. When people start breaking up into factions, just because of disagreements, the resulting weakness will most certainly lead to defeat.
