Muhammad bin Jubair bin Mut’im narrated from his father, who heard in the Farewell Pilgrimage on the day of Arafah, the sermon of the Messenger of Allah (peace be upon him):“O people! Indeed, I do not know whether after today I will be able to meet you again at this place. So may Allah have mercy on the person who heard my words today and remembered them. Some who learn jurisprudence (fiqh) are not themselves jurists, and many who carry jurisprudence convey it to someone more knowledgeable than themselves. And O people! Know that your wealth and your blood are sacred to each other just as the sanctity of this day, this month, and this city. And listen! Hearts will not betray in three things: making deeds sincere for Allah, being sincere with the rulers, and adhering to the community of Muslims. Indeed, their supplication encompasses them.”(That is, the supplication surrounds them for protection from calamities and afflictions.)
