(Unlike Muslims), the other religious groups did not have a universal mission, and the holy war was not a religious duty to them, save only for purposes of defence... They are merely required to establish their religion among their own people. This is why the Israelites after Moses and Joshua remained unconcerned with royal authority for about four hundred years. Their only concern was to establish their religion... The Israelites dispossessed the Canaanites of the land that God had given them as their heritage in Jerusalem and the surrounding region, as it had been explained to them through Moses. The nations of the Philistines, the Canaanites, the Armenians, the Edomites, the Ammonites, and the Moabites fought against them. During that time political leadership was entrusted to the elders among them. The Israelites remained in that condition for about four hundred years. They did not have any royal power and were harassed by attacks from foreign nations. Therefore, they asked God through Samuel, one of their prophets, that he permit them to make someone king over them. Thus, Saul became their king. He defeated the foreign nations and killed Goliath, the ruler of Philistines. After Saul, w:David became king, and then Solomon. His kingdom flourished and extended to the borders of the land of the Hijaz and further to the borders of Yemen and to the borders of the land of the Byzantines. After Solomon, the tribes split into two dynasties. One of the dysnaties was that of the ten tribes in the region of Nablus, the capital of which is Samaria(Sabastiyah), and the other that of the children of Judah and Benjamin in Jerusalem. Their royal authority had had an uninterrupted duration of a thousand years.

When civilization [population] increases, the available labor again increases. In turn, luxury again increases in correspondence with the increasing profit, and the customs and needs of luxury increase. Crafts are created to obtain luxury products. The value realized from them increases, and, as a result, profits are again multiplied in the town. Production there is thriving even more than before. And so it goes with the second and third increase. All the additional labor serves luxury and wealth, in contrast to the original labor that served the necessity of life.

It should be known that at the beginning of a dynasty, taxation yields a large revenue from small assessments. At the end of the dynasty, taxation yields a small revenue from large assessments.
