Anas:
Allah's Messenger (ﷺ) went towards the Khandaq (i.e. Trench) and saw the Emigrants and the Ansar digging
in a very cold morning as they did not have slaves to do that for them. When he noticed their fatigue
and hunger he said, "O Allah! The real life is that of the Here-after, (so please) forgive the Ansar and
the Emigrants." In its reply the Emigrants and the Ansar said, "We are those who have given a pledge
of allegiance to Muhammad that we will carry on Jihad as long as we live."
