It is narrated from Hazrat Anas (may Allah be pleased with him) that I saw the Prophet (peace and blessings be upon him) performing eight rak'ahs of Duha prayer while on a journey, and after completing the prayer, the Prophet (peace and blessings be upon him) said: "I have performed a prayer of longing and fear. I asked my Lord for three things; He granted me two and withheld one. I requested that my Ummah not be destroyed by famine, and Allah accepted it. I requested that the enemy not be given complete dominance over them, and Allah accepted that as well. Then I presented the third request that they not be divided into different sects, but Allah did not grant this."
