O my Lord! Thou hast given me (something) of sovereignty and hast taught me (something) of the interpretation of events - Creator of the heavens and the earth! Thou art my Protecting Guardian in the world and the Hereafter. Make me to die muslim (unto Thee), and join me to the righteous.

Chapter: The neame: 'Al-Hazn'
Narrated 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).
