ٱلَّذِينَ أُخْرِجُوا مِن دِيَٰرِهِم بِغَيْرِ حَقٍّ إِلَّآ أَن يَقُولُوا رَبُّنَا ٱللَّهُ ۗ وَلَوْلَا دَفْعُ ٱللَّهِ ٱلنَّاسَ بَعْضَهُم بِبَعْضٍ لَّهُدِّمَتْ صَوَٰمِعُ وَبِيَعٌ وَصَلَوَٰتٌ وَمَسَٰجِدُ يُذْكَرُ فِيهَا ٱسْمُ ٱللَّهِ كَثِيرًا ۗ وَلَيَنصُرَنَّ ٱللَّهُ مَن يَنصُرُهُٓ ۗ إِنَّ ٱللَّهَ لَقَوِىٌّ عَزِيزٌ

When servants of God opt for the path of God, they are not alone in this world. When heedless, arrogant people make them the target of their persecution, God takes the side of the devotees against the persecutors. Initially God tests the sincerity of his proponents. But then He comes to the help of those who, having undergone this test have proved their sincerity. He creates such circumstances for them as may help them to overcome all kinds of hurdles and continue to adhere to the Truth. The real task of the believers is solely to keep calling people to the truth. Once launched on this course, they remain steadfastly upon it. They sometimes wage war, if necessary, but their war is always defensive, never aggressive. If a group remains in power for a long time, it becomes arrogant and boastful. Therefore, God has devised the law of ‘repelling’ for this world. He manages again and again, to dislodge one group from power through another group. Thus the political balance of power has remained steady throughout history. If God did not resort to this method, then human high-handedness would grow to such an extent that even sacred institutions like places of worship would not remain safe from the depredations of the wicked.
