Ibn Juraij said to me: O Hasan! Ubaidullah bin Abi Yazid informed me that Ibn Abbas said: "A man came to the Prophet and said: 'O Messenger of Allah! I had a dream at night while I was sleeping in which I was praying behind a tree, when I prostrated the tree prostrated along with me. Then I heard it saying: (Allahummaktuh li biha indaka ajran, wad a anni biha wizran, waj'alha li biha indaka dhukhran, wa taqabbalha minni kama taqabbaltaha min abdiki Dawud.)" (O Allah! Record for me, a reward with You for it, remove a sin for me by it, and store it away for me with You, and accept it from me as You accepted it from Your worshipper Dawud). Al-Hasan said: "Ibn Juraij said to me: 'Your grandfather said to me: 'Ibn Abbas said: 'So the Prophet recited (an Ayah of) prostration then prostrated.'" (He said) "So Ibn Abbas said: 'I listened to him, and he was saying the same as the man informed that the tree had said.'"
