(33:33)[^139] Both Sunni and Shi`ite scholars unanimously agree that these four persons took part in Mubahalah together with the Holy Prophet.[^140] Emphasized this great virtue, Sa`d ibn Abi-Waqqas is reported to have said, “When the verse of Mubahalah was revealed to the Holy Prophet, he called `Ali, Fatimah, Hasan and Husayn, saying “O God, these are my Household.”[^141] Having reported the issue of Mubahalah and `a’ishah's narration, al-Zamakhshari says, “This issue is the most rationale for the virtue and righteousness of the Holy Prophet's Household.”[^142] After narrating the event of Mubahalah, al-Bayzawi, says, “This indicates the righteousness of the Holy Prophet and the virtue of his Household.”[^143] In his book entitled Sa`d al-Su`ud, Sayyid Ibn tawus writes, “Muhammad ibn al-`Abbas ibn Marwan, in his book of Ma Nazala min al-Qur'an fi al-Nabi wa Ahli Baytihi, has narrated the event of Mubahalah on the authority of fifty-one reporters among whom were grand companions of the Holy Prophet.”[^144] At the end of this article, it is worth mentioning that there are disagreements concerning the year, month and day of the Mubahalah.[^145] The Event of Ghadir and the introducing of the future leader On his return from the Farewell Pilgrimage on the eighteenth of Dhu’l-Hijjah, and on the land of Ghadir Khumm[^146] which is three miles away from al-Juhafah, the following verse was revealed to Holy Prophet: “O Apostle!

Deliver what has been revealed to you from your Lord; and if you do it not, then you have not delivered His message (5:67)” He therefore ordered the caravan of one hundred thousand pilgrims to stop on that arid land and in that extremely hot weather. Having performed the Noon Prayer, he climbed a high location and delivered a sermon in which he informed of his near death. Then, he asked the Muslims' views on his prophethood. Every one confirmed that he had perfectly conveyed the Divine Message.

He then put stress on the Holy Book and his Household, recommending Muslims not to leave these two lest they would be misled. These two, he added, shall never depart one another until they join him on the Resurrection Day; therefore, Muslims should follow them closely. Then, he took `Ali's hand, raised it and introducing him as the future leader of Muslims, saying: “God is my Master and I am the master of the believers; so, anybody whose master is I, `Ali is now his master.
