The Weeping Date Palm is a Jinn and Oracular Tree in Islamic lore. It was believed to have relentlessly wept until the prophet Mohammad comforted it. Unlike most plants or trees, it can actually get depressed.
The prophet Muhammad, when delivering his sermons, used to stand by or lean on a date palm tree. When a pulpit was built elsewhere and Muhammad started to give his sermon from the pulpit, the tree began to cry like a child. Muhammad then descended from his pulpit and consoled the tree by embracing it and stroking it. The Prophet said, "It was crying for [missing] what it used to hear of religious knowledge given near to it." This incident is recorded in the authentic Islamic Hadith Traditions and is said to have been witnessed by everyone present at the congregation.
