"Indeed, you should not desire to weigh with the intellect the issues of Tawhīd and the Hereafter; the reality of Prophethood; the reality of divine attributes and every other thing beyond the scope of the intellect, for such a desire is futile. An example of this would be a man who has a scale used for weighing gold suddenly desiring to weigh mountains with it! This does not mean that the scale is wrong in its measures; rather, the intellect has a limit it cannot surpass and a boundary it cannot transcend."

“Religious propaganda gives a dynasty at its beginning another power in addition to that of the group feeling it possessed as the result of the number of its supporters... This happened to the Arabs at the beginning of Islam during the Muslim conquests. The armies of the Muslims at al-Qadisiyah and at the Yarmuk numbered some 30,000 in each case, while the Persian troops at al-Qadisiyah numbered 120,000, and the troops of Heraclius, according to al-Waqidi, 400,000. Neither of the two parties was able to withstand the Arabs, who routed them and seized what they possessed.”

“When civilization 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.”

“The only people who accept slavery are the Negroes, owing to their low degree of humanity and proximity to the animal stage. Other persons who accept the status of slave do so as a means of attaining high rank, or power, or wealth, as is the case with the Mameluke Turks in the East and with those Franks and Galicians who enter the service of the state .”

“Royal authority is a noble and enjoyable position. It comprises all the good things of the world, the pleasures of the body, and the joys of the soul. Therefore, there is, as a rule, great competition for it. It rarely is handed over , but it may be taken away. Thus, discord ensues. It leads to war and fighting, and to attempts to gain superiority.”

“Arabic writing at the beginning of Islam was, therefore, not of the best quality nor of the greatest accuracy and excellence. It was not of medium quality, because the Arabs possessed the savage desert attitude and were not familiar with crafts. One may compare what happened to the orthography of the Qur’an on account of this situation. The men around Muhammad wrote the Qur’an in their own script which, was not of a firmly established, good quality. Most of the letters were in contradiction to the orthography required by persons versed in the craft of writing.... Consequently, . No attention should be paid in this connection with those incompetent that knew well the art of writing and that the alleged discrepancies between their writing and the principles of orthography are not discrepancies, as has been alleged, but have a reason. For instance, they explain the addition of the alif in la ‘adhbahannahU "I shall indeed slaughter him" as indication that the slaughtering did not take place . The addition of the ya in bi-ayydin "with hands ," they explain as an indication that the divine power is perfect. There are similar things based on nothing but purely arbitrary assumptions. The only reason that caused them to is their belief that would free the men around Muhammad from the suspicion of deficiency, in the sense that they were not able to write well. They think that good writing is perfection. Thus, they do not admit the fact that the men around Muhammad were deficient in writing.”

“While it is true that many Muslim scholars who composed their works in Arabic, both in the religious and in the intellectual sciences, have been of non-Arab descent, Ibn Khaldūn's use of the term Arab in his history seems to indicate a class of people and not a group. Most scholars believe that, in many instances, Ibn Khaldūn uses the name Arab to mean bedouin. Other scholars, such as Mohamed Chafik, deny this.”
