(2:199) After sunset, the Holy Prophet left `Arafat.[^136] Due to its different aspects of significance, this pilgrimage is called by different titles: Farewell Pilgrimage (Hijjat al-Wada`), the Islamic Hajj (Hijjat al-Islam) and the Conveyance Pilgrimage (Hijjat al-Balagh).[^137] The Prophet's Historical Sermon During his farewell pilgrimage on the day of `Arafah, on the desert of `Arafat, and among all pilgrims, the Holy Prophet delivered a very significant and historical sermon in which he spoke about important issues and declared specific recommendations.

As the attendants testified to the sacredness of that month (Dhu’l-Hijjah) and the sacredness of that day (Yawm `Arafah), the Holy Prophet declared: O people! Up to the day on which you will meet God, your blood and property are as sacred as this month and this day; making aggression against them is forbidden. The bloodshed at the era of negligence and ignorance could not be prosecuted at this time; furthermore, usury is forbidden now.

The Holy Prophet then considered as blasphemy the changing and delaying of the Forbidden Months. Concerning women's rights, he emphatically said, Act kindly to women since they are God's assets in your hands and are made legal for you through Divine laws. Let those who are present inform others that there shall be no prophet after me and there shall be no ummah after you, Muslims.

Towards the end of his speech, the Holy Prophet declared null and void the customs and ceremonies of the Ignorance Era.[^138] A great virtue Great scholars have pointed out that it was a great point of honor for these four persons; namely, `Ali, Fatimah, Hasan and Husayn to take part in that Mubahalah together with the Holy Prophet. This is because this event showed that Hasan and Husayn are the sons of the Holy Prophet and they, together with Imam `Ali, are his true life.

Fatimah, his daughter, was the only woman who had taken part in the ceremony of Mubahalah and the word nisa' could only refer to her. `a'ishah is reported to have said that on the day of Mubahalah, the Holy Prophet asked these four persons to gather under his black clock. He then reciting this verse of the Holy Qur'an: Allah only desires to keep away the uncleanness from you, O people of the house, and to purify you a thorough purifying.
