Allah (Most High) says:
وَمَنْ أَظْلَمُ مِمَّنْ مَنَعَ مَسَاجِدَ اللَّهِ أَنْ يُذْكَرَ فِيهَا اسْمُهُ وَسَعَىٰ فِي خَرَابِهَا ۚ أُولَٰئِكَ مَا كَانَ لَهُمْ أَنْ يَدْخُلُوهَا إِلَّا خَائِفِينَ ۚ لَهُمْ فِي الدُّنْيَا خِزْيٌ وَلَهُمْ فِي الْآخِرَةِ عَذَابٌ عَظِيمٌ
“Who could do greater wrong than someone who bars access to the mosques of Allah, preventing His name from being remembered in them, and goes about destroying them? Such people will never be able to enter them – except in fear. They will have disgrace in the dunya and in the akhira they will have a terrible punishment.”
There is only one solution to this crisis which is military intervention by Muslim armies to meet the tyrannical oppression of the apartheid state of Israel. Since these armies will not move except under a sincere Muslim leader, a Caliph then appointing a Caliph becomes wajib according to the principle, “that which is necessary to accomplish a wajib is itself wajib.” He will then lead them as their commander in-chief to victory by the permission of Allah (Most High).
وَلَوْلَا دَفْعُ اللَّهِ النَّاسَ بَعْضَهُمْ بِبَعْضٍ لَهُدِّمَتْ صَوَامِعُ وَبِيَعٌ وَصَلَوَاتٌ وَمَسَاجِدُ يُذْكَرُ فِيهَا اسْمُ اللَّهِ كَثِيرًا ۗ وَلَيَنْصُرَنَّ اللَّهُ مَنْ يَنْصُرُهُ ۗ إِنَّ اللَّهَ لَقَوِيٌّ عَزِيزٌ
“If Allah had not driven some people back by means of others, monasteries, churches, synagogues and mosques, where Allah’s name is mentioned much, would have been pulled down and destroyed. Allah will certainly help those who help Him – Allah is All-Strong, Almighty”
