Ghazi Abdurahman Al-ghosaibi is considered one of the most prominent writers in Kingdom Of Saudi Arabia and one of its shrewd critics.  He used humor a lot in his works, and his humor wore a historical, political, social, cultural and economic guise, as he employed it for his strict and sharp stances towards the failed Arab regimes in a gtay tone, and towards the colonial Western regimes in a stark black tone. Our subject intends to study the art of humor and its role in the novel Abu Shalakh Al-Barmai by Ghazi Al-Qusaibi, and the semantic meanings it carries with it, and how to use humor in the fictional text in terms of formality and meaning, on the basis of the descriptive-analytical sciences. Al-Qusaibi does not only intend to make the reader laugh, but rather he intends and aims to search for pains and fears suffered by life and the global and Islamic community in all times and all places. The writer intends to correct the reality of the nation and society through the bitter and stinging humorous criticism, revealing the stupidity and naivety of society and the cleverness of rulers and states in exploiting this naivety. Al-Qusaibi's humor has two basic features: First, in terms of significance, it carries within it revolutionary meanings that denounce political, social, cultural, and economic regimes around the world, especially in Arab academies. Secondly, in terms of wording, it was formulated in blatant language and a strong and overwhelming tone that descended on the heads of the regimes that betrayed the Arab and global causes, especially the Islamic world, like a crushing hammer that broke heads. In the end, we discuss the writer's most prominent methods of expressing concepts in a humorous way. In the end, we studied the most important semantic methods of humor in the novel, and what are the most prominent ones.
