What is the ruling on reciting poems that contain much praise and boasting, such as "We are the house of glory and grace, and we have never been ignoble, for we have not hungered except in fasting, and we have not tired except in standing [in prayer]. We were raised upon noble deeds, and our descent upon the land is peace"?

Poetry, its good is good and its bad is bad, and it is judged based on its content. As for boasting and vainglory, they are reprehensible and are forbidden by Islamic law. They are considered degrees of arrogance, like showing off one's virtues and lineage, and acting superior to people by enumerating one's merits, and self-praise and commendation. The Messenger of Allah (peace be upon him) said: "Indeed, Allah has revealed to me that you should be humble, so that no one oppresses another, and no one boasts over another." The forbidden boasting includes showing off in oneself or one's ancestors, which many hadiths have prohibited, such as the hadith of Abu Hurairah (may Allah be pleased with him): "Indeed, Allah عز وجل has removed from you the haughtiness of the Jahiliyyah (pre-Islamic era) and its boasting about ancestors. A believing, pious person, and a wicked, wretched person. You are the children of Adam, and Adam was created from dust. Let men abandon their boasting about peoples, for they are but coals from the coals of Hell, or they will be more insignificant to Allah than the beetles that push with their noses the filth."
