Abdullah bin Khabbab (may Allah have mercy on him) narrated from his father: the Messenger of Allah (peace and blessings be upon him) prayed a prayer and made it long, so the Companions said: O Messenger of Allah! You prayed a prayer such as you did not used to pray? He (peace and blessings be upon him) said: "Yes, it was a prayer of hope and fear. In it I asked my Lord for three things; He granted me two and withheld one from me. I asked Him not to destroy my Ummah by famine, and He granted me that. I asked Him not to set over them any enemy from other than them, and He granted me that. And I asked Him not to make some of them taste the violence of others, and He withheld that from me."
