In technical terms, history is the science through which we learn about the lives of kings, prophets, conquerors, and notable figures, as well as the significant events and customs of past eras. It serves as a means to understand the social, ethical, and cultural aspects of bygone times. Some define history as the study of human societies living together, referred to as civilization or "madinah," and the various conditions that naturally affect them. These events are recorded as historical accounts, passed down from predecessors to successors as lessons and examples. Others suggest that the word "history" (tareekh) derives from reversing the root word for delay (takhir), meaning to relate earlier times to later ones, such as noting when a religion, empire, or battle emerged. In essence, history consists of events and accounts recorded in relation to time.
