What are the virtues of the Noble Hadith?

There are multiple virtues and benefits to learning the Prophet's hadiths, peace and blessings be upon him. Among them is that whoever preserves for his Ummah forty hadiths concerning its religion, Allah will raise him on the Day of Resurrection among the ranks of jurists and scholars (though this hadith is weak). Another benefit is the radiance of the face in this world and the hereafter for anyone who hears a hadith, memorizes it, and conveys it to others. The fundamental knowledge is a definitive verse, an established Sunnah, or a just obligation.
