What did the Prophet Muhammad (saw) ask of Allah (swt) when he visited the Emigrants and Ansar while they were digging a trench?
 Narrated Sahl:                     Allah's Apostle came to us while we were digging the trench and carrying out the earth on our backs. Allah's Apostle then said, "O Allah ! There is no life except the life of the Hereafter, so please forgive the Emigrants and the Ansar."
