Is it permissible to say that "the Sayyids" (descendants of Al-Hasan and Al-Husayn) are "the offspring of the Prophet's beast," and is this considered a mockery of them and an insult to the Companioness Fatimah?

A Muslim must respect, love, support, and honor the household of the Prophet, peace and blessings be upon him, for Allah Almighty says: (Say, "I ask not of you any reward for it, save affection for [my] kin.") [Quran 42:23]. And Al-Shafi'i says about them: "O Household of the Messenger of Allah, your love is an obligation upon people, revealed in the Quran. It suffices you as immense pride that whoever does not send blessings upon you, his prayer is not valid." The foremost among those who deserve respect and appreciation is Fatima Al-Zahra, for the Prophet, peace and blessings be upon him, said to her: "Are you not pleased that you are the mistress of the women of the worlds?" and his saying: "Indeed, Fatima is a part of me." Therefore, Muslims must respect her, appreciate her, and mention her with the best description, without exaggeration.
