The author highlights how the political picture of the Umayyad era influenced literary life. It is well known, that the period of ruling of the Umayyad caliphs was full of endless wars, conflicts, instability, and yet, despite this, this is the era of great conquests in the history of the Arabs. At that time, when the unrest in the country was at its peak, as well as when the greatest things in the history of the Arabs took place, the Arab rulers themselves also made various speeches.

At the end of the article, the author carefully analyzes the speech of one of the governors of the Umayyads Ubaidullah bin Ziyad as an example of public speaking and literary heritage.
21 patients with a severe course of COVID-19 were under observation. The study was carried out in a specialized hospital for the treatment of patients with coronavirus infection.
