Islamic administration in the heyday of the Arabs

Some researchers in the affairs of Islam in its early era often tried to portray the Arabs in a way other than their image, in deference to the desires of the souls, and to draw incomplete conclusions in their rulings on the Messenger, may God bless him and grant him peace, and to turn a blind eye to some of his companions, and to lean heavily on Islamic civilization, claiming The Arabs, even in Islam, did not do anything significant in terms of civilization, and that they imitated in all their actions what they added to what they learned from the Romans and Persians in terms of methods. Civilization.
If what they said was true, the laws of Persia and the Romans would have been valid and sufficient for their purpose, and the Arabs would not have been able to remove the authority of those two great nations from the most beautiful parts of the earth, and to rule and organize them according to an innovative example the likes of which the country has hardly witnessed.
Islam innovated and innovated in war, administration, and politics, just as it innovated and innovated in science, legislation, and civil causes, as is evident in the pages of Islamic history.
