Then he (peace and blessings be upon him) said: 'Do you know why I have done this with you?' I submitted: 'No!' So the Prophet (peace and blessings be upon him) said: 'When two Muslims meet one another, shake hands with one another and meet one another with a cheerful face, then when they do this, they are both forgiven before they part.'" (Allamah al-Haythami says:) I say: Abu Dawud has recorded this narration in abridged form.
