It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he said: I was present in the gathering of the Prophet (peace and blessings be upon him) when a Bedouin came to him (peace and blessings be upon him), and he (peace and blessings be upon him) asked him: "Do you have any desire for something good? (It is) that you bear witness that there is no god worthy of worship except Allah and that Muhammad (peace and blessings be upon him) is the Messenger of Allah." He asked: "Who will bear witness for you to this truth?" He (peace and blessings be upon him) said: "This tree." Then he (peace and blessings be upon him) called that tree, which stood on the edge of the valley, and it came moving very swiftly until it stood right in front of him (peace and blessings be upon him). He (peace and blessings be upon him) asked it to bear witness, and it bore witness (to his messengership and to Allah's oneness) three times, and then it returned to its place. At this the Bedouin said: "I will go to my people; if they accept what I say, I will bring them to you as well; otherwise I will return to you myself and remain in your company."
Imam al-Bazzar and Imam al-Hasan bin Sufyan have also narrated it through the route of Ibn Fudayl, and Imam Ibn Hibban declared this hadith sahih (authentic).
