Al-Musaiyab:
That his father (Hazn bin Wahb) went to the Prophet (ﷺ) and the Prophet (ﷺ) asked (him), "What is your
name?" He replied, "My name is Hazn." The Prophet (ﷺ) said, "You are Sahl." Hazn said, "I will not
change the name with which my father has named me." Ibn Al-Musaiyab added: We have had
roughness (in character) ever since.
Narrated Al-Musaiyab:
on the authority of his father similarly as above (i.e., 209).
