Qur’an is the basic source of knowledge in Islam.The explanation of Qur’an was done by Prophet صلى الله عليه و سلام, which is in the form of Hadith and Sunnah.
The revelation the Holy Prophet صلى الله عليه و سلام received from Allâh is of two kinds:
(i) the revelation of the Qur’ân, named in the Islamic terminology as al-wahi-e-matlu (the recited revelation, i.e. the revelation which can be recited in the prayers). This kind of revelation is confined to the verses of the Qur’ân and is written verbally in its folds.
(ii) the revelation received by the Prophet صلى الله عليه و سلام from time to time to let him know the pleasure of Allâh in day-to-day affairs and the details of the principles laid down in the Qur’ân with their correct interpretation. This kind of revelation is calledal-wahi-e- ghair matlu (the unrecited revelation). This kind of revelation is not conveyed to the people VERBALLY. It has been demonstrated through the sayings and acts of the Prophet صلى الله عليه و سلام.
Hadith is not the personal opinion or desire of Prophet صلى الله عليه و سلام, instead it was from ALLAH.The Evidence is in
Surah An-Najm Ayah 3 and4, Allah says,“ Nor does he speak of (his own) desire. It is only an Inspiration that is inspired”.

Question :What is the purpose of gaining knowledge of Hadith?
Answer :The purpose of gaining knowledge of Hadith, is to follow Prophet and act upon his teachings. Because our actions are valid and will be accepted on the day of judgement because of two reasons :
1-Intention only for the sake of ALLAH.
2- According to the Sunnah of Prophet.
Evidence from Surah Mohammad Ayah 33, ” O you who believe! Obey Allah, and obey the Messenger (Muhammad ) and render not vain your deeds.”
“and render not vain your deeds.” means don’t waste your deeds.On the day of judgement good deeds of those people will be wasted, those who didn’t did according to the Sunnah of Prophet.
