It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that he says: The Messenger of Allah, peace and blessings be upon him, said: I made three supplications to my Lord; He accepted two of them and did not accept one. I supplicated that He would not afflict my Ummah with a general famine, and He accepted this supplication. Then I made a second supplication that the enemies of my Ummah would not prevail over them, and He also accepted this supplication. And I made a third supplication that He would save them from being divided into different groups, but Allah Almighty did not accept this supplication of mine.
