Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: On the occasion of the Battle of Khandaq, the Ansar recited these verses: "We are the people who have pledged allegiance to Muhammad (peace be upon him) that as long as we live, we will continue to strive (in jihad)." So the Prophet (peace be upon him) replied to them by reciting this verse: "True life is only the life of the Hereafter. (O Allah) honor the Ansar and the Muhajirin."
