Ibn Musayyib narrates from his father that the Noble Prophet (peace and blessings be upon him) asked his grandfather: "What is your name?" He replied: "Huzn (hardship)." The Prophet (peace and blessings be upon him) said: "No, rather you are Sahl (ease)." He said: "But the name my father has given me, I will not change it." Ibn Musayyib said: "So, harshness and roughness always remained in our family."
