It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that Jibreel (Gabriel), peace be upon him, came to the Messenger of Allah, peace and blessings be upon him, while he was being persecuted by the people of Makkah, the Quraysh, covered in blood, sitting sad and grieved. Jibreel, peace be upon him, said: O Messenger of Allah! Do you wish that I show you a sign (of Allah’s power)? The Prophet, peace and blessings be upon him, said:“Yes, show me.”So Jibreel, peace be upon him, looked at a tree that was behind him and said: Call it. The Prophet, peace and blessings be upon him, called the tree, so it came and stood before him. Jibreel, peace be upon him, said: Command it to return. So he commanded it, and it returned. The Prophet, peace and blessings be upon him, said:“Enough, enough”(meaning this sign is sufficient for me).
