One of the good-doers saw the Prophet of God (a.s.) in his dream. He asked the Prophet (S), ‘O Prophet of God! Which of your offspring should I go to visit?’ The Prophet (S) said, ‘A few of my descendants who have been poisoned have come to me. Also a few of my offspring who have been murdered have come to me.’ Then he asked the Prophet (S), ‘O Prophet of God! Given the great distances between their shrines (or locations), which one of them do you recommend me to go and visit?’ The Prophet (S) said, ‘Visit the one who is closest to you - that is whom you are near to and is buried in the land of loneliness.’ Then he asked the Prophet (S), ‘O Prophet of God! Do you mean Ar-Ridha’ (a.s.)?’ God’s Prophet (S) said, ‘Say: God’s Blessings be upon him. Say: God’s blessings be upon him three times.’”
