If I could live in any time in history and in any country, I wish that I lived in the golden period of the Umayyad Caliphate. When Omar bin Abdulaziz was the caliph, the golden period of the Umayyad Caliphate started. He did many great reforms, for example, unpaid labor was made illegal, and state officials were excluded from entering into any business. Also, he evenly distributed pasturelands and game reserves, which were reserved for the family of the dignitaries, among the poor for the purpose of cultivation. Generally, Omar ordered the first collection of hadith, or sayings and actions of Mohammed material in an official manner, fearing that some of it might be lost, so, the first collection of hadith was in Omar’s era. Moreover, Omar approached the Caliphate unlike any other Umayyad Caliph has done before him. He was extremely pious and disdainful of worldly luxuries. In dead, although Omar's reign was very short (three years), he is very highly regarded in Muslim memory. And I still remembered his message, which is “There are five things which if a judge missed any of them, it will be a blemish on him: A judge should be discerning, deliberate, chaste, resolute, knowledgeable and inquisitive.”(1). So, I hope that our kings follow this message.
