Concept:The farewell sermon, known as Khutbat al-Wada, was delivered by Prophet Muhammad (SAW) during his final pilgrimage.
Explanation:In this sermon, the Prophet gave final and comprehensive guidance to the Muslim community.
He spoke about the sanctity of life, property, and honour.
He also reminded Muslims of the importance of unity and brotherhood.
Most importantly, he directed Muslims to hold fast to two lasting sources of guidance.
The first is the Book of Allah, which is the Qur'an.
The second is the Sunnah, which refers to the sayings, actions, and approvals of the Prophet.
The Prophet taught that whoever clings to these two will not go astray.

Rather, he pointed Muslims to the Qur'an and the Sunnah as their complete and permanent guide.
