with your molars; and beware of newly-introduced matters, for every innovation is misguidance.” Narrated by Abū Dāwūd and al-Tirmidhī, who said: “A ḥadīth that is ḥasan ṣaḥīḥ (sound and fair).”

nawājidh—with a dotted dhāl—are the canine teeth; some scholars say the term refers to the molars.

[Explanation]
The author—may Allah have mercy on him—cites in the chapter on safeguarding the Sunnah and observing its etiquette the report of al-ʿIrbāḍ b. Sāriyah (may Allah be pleased with him): “The Messenger of Allah ﷺ delivered an eloquent sermon that made our hearts tremble and our eyes shed tears.” This was the Prophet’s practice ﷺ: at times he would give scheduled sermons—such as the Friday sermon and the two festival sermons—and at other times he would preach on special occasions. Whenever a situation called for admonition, he ﷺ would rise and address the people.

Among those sermons is the address he gave after the eclipse prayer; it was a tremendous, moving sermon. Whoever wishes to consult it should refer to Zād al-Maʿād by Ibn al-Qayyim (d. 751 AH).

Here he says: “He delivered an eloquent sermon that caused our hearts to tremble and our eyes to shed tears.” “Tremble” (wajilat) means they were filled with fear, and their eyes “shed tears” out of weeping. The sermon had a profound effect on them, so much so that they said, “O Messenger of Allah, it seems as though this is a farewell exhortation, so give us counsel.”
