Silsilat al-Ahadith al-Sahihah

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that during the digging of the trench, the companions of the Messenger of Allah (peace and blessings be upon him) used to say: "We are those who have pledged allegiance to Muhammad (peace and blessings be upon him) to strive in jihad as long as we live." And the Noble Prophet (peace and blessings be upon him) would say: "O Allah! True goodness is the goodness of the Hereafter, so forgive the Ansar and the Muhajirun." Barley bread and a dish with a bad smell were brought to the Messenger of Allah (peace and blessings be upon him), but all of them ate it, and the Noble Prophet (peace and blessings be upon him) said: "The goodness of the Hereafter is the real goodness."
