Musannaf Ibn Abi Shaybah

Hazrat Hudhaifah (may Allah be pleased with him) bin Al-Yaman narrates that the Messenger of Allah (peace and blessings be upon him) went towards the place of Harrah near the tribe of Banu Muawiyah, and I also followed behind him, until the Prophet (peace and blessings be upon him) reached there. Then the Prophet (peace and blessings be upon him) performed eight rak‘ahs of Duha prayer, and he made them very long. Then the Prophet (peace and blessings be upon him) returned and said, "O Hudhaifah (may Allah be pleased with him)! Did I make it too lengthy for you?" I replied, "Allah and His Messenger (peace and blessings be upon him) know best." The Prophet (peace and blessings be upon him) said, "I asked Allah for three things in this prayer. Allah granted me two of my supplications and withheld one. I asked Allah that my Ummah would never be overcome by outsiders, so Allah granted my supplication. And I asked that my Ummah would not be destroyed by famine, so Allah granted this supplication as well. And I asked that there would be no fighting among my Ummah, but this supplication was not granted."
