“Once I asked abu al-Hassan (a.s.) ‘May Allah keep my soul in service for your cause, can a man be with a people who speak and laugh at funny stories?’ The Imam said, ‘It is not an offense if there is not that.’ I (the narrator) then thought ‘ that ’ was his signal to indecent acts. The Imam then said, ‘Arabs would come to the Messenger of Allah and bring him gifts and then say, “Pay us for our gifts.” The Messenger of Allah would laugh. When he felt sad he would say, “What happened to the Arab man? I wish he comes by.’””
