Narrated Sahl bin Sa`d As-Sa`idi
We were in the company of Allah's Messenger (ﷺ) in (the battle of) Al-Khandaq, and he was digging the trench while we were carrying the earth away. He looked at us and said, "O Allah! There is no life worth living except the life of the Hereafter, so (please) forgive the Ansar and the Emigrants."
