Narrated Anas: The Emigrants and the Ansar started digging the trench around Medina carrying the earth on their backs and saying, "We are those who have given a pledge of allegiance to Muhammad that we will I carry on Jihad as long as we live." The Prophet kept on replying, "O Allah, there is no good except the good of the Hereafter; so confer Your Blessings on the Ansar and the Emigrants."

Narrated Al-Bara: The Prophet went on carrying (i.e. the earth) and saying, "Without You (O Allah!) we would have got no guidance."

Narrated Al-Bara: On the day (of the battle) of Al-Ahzab (i.e. clans) I saw the Prophet carrying earth, and the earth was covering the whiteness of his `Abdomen. And he was saying, "Without You (O Allah!) we would have got no guidance, nor given in charity, nor prayed. So please bless us with tranquility and make firm our feet when we meet our enemies. Indeed (these) people have rebelled against (oppressed) us but never shall we yield if they try to bring affliction upon us."
