Abstract
This research discusses a significant problem regarding the elimination of financial waste and its social effects during the era of Caliph Omar Ibn Abdul Azīz (99-101 AH), the Caliph who occupied a great position in the history of the Umayyad state. During Omar’s reign, which lasted only for two years and a few months, people felt positive transformations in their lives, progress in their country, improvement in their livelihood, and a feeling of security that spread throughout the state. During his short term of rule, Caliph Omar Ibn Abdul Azīz showed skillful statesmanship, great abilities and distinguished competence in uplifting the economy through various means and providing all the members of the society with a decent social life. The research will focus on recording the change that Caliph Omar Ibn Abdul Azīz brought about in the life of the nation by explaining the rampant financial waste in the state before he took power and how he eliminated it by achieving justice and equality among the governors and princes and the subjects at large.
