What example did Prophet Muhammad (saw) set during the Trench that he asked Allah (swt) to grant forgiveness for the Emigrants and the Ansar?
 Narrated Sahl bin Sa`d:                     We were with Allah's Apostle in the Trench, and some were digging the trench while we were carrying the earth on our shoulders. Allah's Apostle said, 'O Allah! There is no life except the life of the Hereafter, so please forgive the Emigrants and the Ansar."
