Concept:Hadith is the preserved record of the Prophet's sayings, actions, and approvals, which serves as the practical guide to Islam after the Qur'an.
Explanation:The Prophet's message is not limited to the Qur'an alone.
Muslims need his explanations and living example to understand how to practise the faith.
Hadith preserves this guidance and passes it down to later generations.
It clarifies the Qur'an, explains acts of worship, and gives moral direction.

Therefore, hadith is important because it is the means through which the Prophet's message is known.
