I have repeatedly invited the Muslim governments to unity and brotherhood vis-a-vis the foreigners and their mercenaries. They want to sow discord among the Muslims and the Muslim governments; to keep our esteemed Muslim governments in bondage and submission to imperialism; and to use their spiritual and material resources .
I have repeatedly warned the governments, in particular the government of Iran, of Israel and its perilous agents. This cancerous gland that has been planted in the heart of the Islamic lands with the support of the powerful imperialist countries and whose roots of corruption are threatening the Muslim countries every day, should be uprooted through the determination and concerted efforts of the Muslim countries and the great Muslim nations. Israel has committed armed uprising against the Muslim countries; thus, its annihilation is a necessity for the Muslim governments and their nations. Assisting Israel, whether in the form of selling weapons and ammunitions, or oil, is unlawful haram [and contrary to Islam. Relations with Israel and its agents, whether political or trade relations, is unlawful and contrary to Islam. The Muslims must stop using Israeli products and goods.
