Sayyiduna Salman bin Amir al-Dabbi (may Allah be pleased with him) narrates: I came to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah! My father used to maintain family ties, honour guests and keep his pledges. He (peace and blessings be upon him) asked: "And he did not live to see Islam?" I said: No. When I turned to leave, he (peace and blessings be upon him) said: "Bring the old man to me." Then he said: "This goodness will continue in your descendants; they will never be humiliated and they will never become destitute."
