What is the legacy of the Prophet (sallallaahu 'alayhi wa sallam)?  Why was he sent?  What was he sent with?  Was he only sent with the Qur'an?  Is Sunnaah important? 

It is one thing to say I believe in the Prophet and it is another thing to believe in the mission of the Prophet (sallallaahu 'alayhi wa sallam).  Unless we realise the importance of his message and how he was deliver it, we will not realize the high status of his sunnah and how we are to follow it.

A great lecture for a great ummah that Allaah (Ta'aalaa) described: You are the best nation coming out of the mankind, enjoining good and forbidding evil.

The greatness of this ummah will be lost if they loose the importance of the mission of the Prophet (sallallaahu 'alayhi wa sallam) in their hearts.
