A hadith like this has been narrated on the authority of 'Ubaidullah b. Abi Yazid.
The Prophet's life was an example for us all, and it is important for us to follow in his footsteps in order for us to be successful in this world and in the hereafter. His words were full of wisdom, compassion, justice, mercy, kindness and love; values which are essential for a peaceful society. We must remember that these values are not only applicable today but will remain relevant throughout time as they have been since their inception over 1400 years ago.
