Huzurﷺ and his companions offered their last Hajj viz. Hajj-tul-Wida and after the departing Tawaf of Ka’aba, which is known as the Tawaful-Wida, left for Medina with the Muhajirins and Ansars. On the they reached a place named Kh where there is a lake. In Arabi, the lake is known as Ghadir; hence this place was also known as a Ghadir-eKham, i.e. a place of the lake. Here he gathered all the Saha’aba-e-Kiram and delivered a lecture (khutba) which consists of the following points:
“All praises to Allah, the Almighty! O, people! I am a human being. Very shortly the messenger of Allah will come to me (with Allah’s message of departure), and I will welcome it. Among you, I leave two very important things: One of them is the Kitab-e-Ilahi, which includes Allah’s Divine Light and His guidance for the true path of life. Hence, hold tightly to this Holy Book.”. He encouraged and created an interest among the people for the Holy Book, and then he added, “The second point is, my descendents. I am reminding you of Allah in connection with my kin relatives and descendents.” Sahih Muslim (Chap: Manakibe Ali, Vol-II).
There are some other points also in Musnad-e-Ahmed, Sunan-e-Nisai, Sunan-e-Tirmizi, Mustadar and Mauzam Kabir Tibrani wherein Huzur ﷺ praises are described.
This source contains the following words even: “Hazrat Ali AlaihisSalam is the abd of the same Master whose abd I too am. O Allah, love those people who love Hazrat Ali AlaihisSalam and those who keep enmity with Hazrat Ali AlaihisSalam, you also be their enemy.This holy order of the Holy Quran is meant for the human beings and subtle living beings. My descendents are my lineage. Hazrat Ali AlahisSalam is the slave of the same Master whose slave I too am.” This is to be repeated over and over again.
This clearly points out that Hazrat Ali AlaihisSalam is also is included in his descendents. And it is clearly indicated that he is one of the kin relatives.Because of this point, he is one of the descendents besides being kin relative.
In this Hadith of Ghadir-e-Kham, the greatness of Hazrat Ali AlaihisSalam has been described. Due to his, this greatness, there is a holy order that Hazrat Ali AlaihisSalam is the slave of the one whose slave I am. The learned people of Ahle-Sunnat consider “Maula’ as ‘beloved.’ The implication of the Hadith from this point of view is, “Hazrat Ali AlaihisSalam also is the beloved for whom I am beloved.” This contains the secret that one who does not love Hazrat Ali AlaihisSalam does not love me too. That means he is not a mo’min. The following Hadith also indicates the same thing in which Huzur told Hazrat Ali AlaihisSalam “O’Ali, one who is momin only will love you, and those who are non-believers will be jealous of you.” From this, it can be judged how great was Hazrat Ali AlaihisSalam to love. Let us refer to the following Hadith in this connection that one day Huzur ﷺ took the hands of Hasnain in his Holy hands and said, “The person who loves me, my grandsons, their father and mother, will be with, and equal to, me on the day of judgement.” This Hadith appears in Masnad-e-Ahmed also. (Kanzul Aamal Vol-VI)
Besides Hazrat Ali AlaihisSalam praises, this Hadith contains the love of Hazrat Fatema AlahisSalam and Hasnain Karimain AlaihisSalam What a marvellous greatness has been shown! Let us listen to one more Hadith on such pure feelings of love: “Any worshipper of Allah who still does not love me is not momin at all until he loves me. I too will have no love for him till he loves my descendents and kin relatives.”
