A man came to Imam Jawad (AS) whilst he was very happy and Imam (AS) asked him: What is happening that you are so happy? That man replied: O’ the son of the Prophet of Islam (PBUH), I heard from your father who said: The best happy day for the human being is when God gives him the success of doing good and charitable deeds and solve the problems of his brethren. Today needy people from different places came to me and by the grace of God their problems were solved and I managed to solve the problems of ten needy people. That is why I am so happy. Imam Jawad (AS) said: Swear to my life, you deserve to be so joyous and happy on the condition that you do not spoil your deeds now and in the future [1].
