It is narrated from Hazrat Anas that the Messenger of Allah, peace and blessings be upon him, came out on a cold morning. The Muhajirun and Ansar were digging the trench. When he, peace and blessings be upon him, saw them, he said: "Indeed, the real life is the life of the Hereafter. So (O Allah!) forgive the Ansar and the Muhajirun." The noble companions replied to him, peace and blessings be upon him: "We are those who have pledged allegiance to Muhammad (peace and blessings be upon him). We will remain steadfast on the duty of Jihad as long as we live."
