According to this Hadith, it is a quality of a Muslim that he is very much concerned about acquiring virtues and doing good, and he is never tired of struggling for them and live by them so much so that in this struggle he reaches the end of his life. By mentioning this Hadith in Kitab-ul-`Ilm it has been made evident that the best of the virtues is learning and teaching of religious knowledge because it is actually this knowledge which enables a person to distinguish between good and evil.
