“…it was weeping for the remembrance it had once heard.” Recorded by al-Bukhari.

Explanation
These dispersed reports which the author—may Allah have mercy on him—placed at the end of Riyad al-Salihin include the hadith of Jabir, and within it lies a sign from the signs of Allah and a proof of the truthfulness of His Messenger ﷺ.

Know that Allah the Exalted has never sent a prophet without granting him signs that human beings could accept as evidence; for had He dispatched a messenger bereft of a sign attesting that he was truly Allah’s envoy, no one would have believed him and people would have had an excuse to reject his call. Yet, by His wisdom and mercy, Allah has never sent a messenger without providing him with signs that compel belief—signs meaning the indicators that attest to his veracity.

The signs bestowed on the Prophet ﷺ are many. Whoever wishes to explore them further should consult two works: first, Al-Jawab al-Sahih liman baddala Din al-Masih, in which Shaykh al-Islam—may Allah grant him abundant mercy—lists, toward the end of the book, both cosmic and legislative signs granted to the Prophet ﷺ, the like of which was given to no one else; and second, Al-Bidayah wa’l-Nihayah by Ibn Kathir—may Allah have mercy on him.

Among those numerous signs is the incident narrated by Jabir: the Prophet ﷺ used to deliver the Friday sermon while leaning against the trunk of a date-palm. When a woman of the Ansar had a pulpit constructed for him, the trunk began to moan like a she-camel separated from its calf, and at times it cried like a small child because it had been parted from the Prophet ﷺ. Allah is indeed Most Great—an inanimate object, a mere palm-tree trunk, weeping because it had been deprived of the Messenger of Allah ﷺ.
