Hadith refers to the speech , reports of statements or actions of Prophet Muhammad (saws) .
Technically Hadith means the narration of the sayings, doings or approvals (Taqrir) of Muhammad (peace be upon him). Taqrir implies that someone did in front of the Muhammad (peace be upon him) and the Muhammad (peace be upon him) observed it and did not condemn it. It means that the person received the tacit approval of Muhammad (peace be upon him) in connection with a particular action.
Different questions are raised while elucidating the importance of Sunnah in Islam. These questions are to be answered in an Islamic, logical and scientific way. Some of the objections and questions that are raised by the critics of Islam are; there is no need to imitate the life of Muhammad (peace be upon him) even though he is the greatest of men. This imitation puts chains on the freedom of an individual. Is there no other system than the system of orders and prohibitions, actions and customs, approvals and disapprovals derived from Muhammad (peace be upon him)? Our future attitude towards Islam will be determined by one process i.e., how we will meet these objections raised against the Sunnah?
Islam is the complete way of life. It brings unity in all aspects of life. We must accept the teachings of the Qur’an and the Muhammad (peace be upon him) in their totality, if not done so; these teachings will lose their importance and value. To know the importance of Hadith in Islam, then it is very important for us to know the position and importance of the person whom we are strictly observing and following. One thing is very clear that human intellect has varied limitations and also Islamic teachings rest on transcendental truths; therefore for their elucidation and explanation, guide is important and the very guide who possesses more than normal reasoning qualities and that guide is no one except Muhammad (peace be upon him).
