It is narrated from Sayyiduna Ubaydullah bin Ubaydullah (may Allah be pleased with him) that when, on the day of Badr, the Messenger of Allah (peace and blessings be upon him) saw the multitude of the polytheists and the small number of the Muslims, he performed two units of prayer, and Sayyiduna Abu Bakr (may Allah be pleased with him) was standing on his right side. Then, in the prayer, the Messenger of Allah (peace and blessings be upon him) said: "O Allah! Do not leave me alone. O Allah! Do not disgrace me. O Allah! Do not deprive me. O Allah! I ask You for the promise which You made to me. O Allah! If this army of the polytheists defeats this army of the Muslims, then Your worship will never be established again." Sayyiduna Abu Bakr (may Allah be pleased with him) said: "May my parents be sacrificed for you! By Allah, Allah will never leave you, nor disgrace you, nor deprive you, and He will surely grant you victory over your enemy as He has promised." Then the Messenger of Allah (peace and blessings be upon him) returned happily and said: "I saw Jibreel (peace be upon him) descending from the sky, wrapped in battle attire with dust on his teeth, and then I realized that this is help (from Allah)."
