Saeed bin Musayyib narrates from his father: The Prophet Muhammad (peace be upon him) asked his grandfather, "What is your name?" He replied, "Huzn (meaning sadness)." The Prophet (peace be upon him) said, "Rather, you are Sahl (meaning ease)." He replied, "I do not wish to change the name that my father gave me." Saeed bin Musayyib says: After that, he always remained sorrowful.
