“History shows that the Muslims increased in civilization and progressed in relation to the power of the truths of Islam; that is, to the degree that they acted in accordance with that power. History also shows that they fell into savagery and decline, and disaster and defeat amidst utter confusion to the degree of their weakness in adhering to the truths of Islam.”

As for other religions, it is quite to the contrary. That is to say, history shows that they increased in civilization and progressed in relation to their weakness in adhering to their religions and bigotry, and were subject to decline and revolution to the degree of their strength in adhering to them. Up to the present, time has passed thus.
