Gadir-Khum holiday

On the eighteenth day of the month of Zil-Hijja, one of the biggest holidays in the Islamic world is the Ghadir-Khum holiday.
It was on this day, in the 10th year of the Hijra, that the Prophet Muhammad, by the order of Allah, appointed His Eminence Ali (a) as his viceroy. Gadir-Khum is a significant event that happened in the oasis of Gadir-Khum.
According to traditions, His Eminence Muhammad (pbuh) along with more than 100 thousand companions, having performed Hajj, left Mecca and went to Medina on the 14th day of the month of Zil-Hijjah. Between Mecca and Medina, near the village of Juhfa, the Ghadir Khum event took place.
When the caravan reached Juhfa, Allah Almighty sent the following verse to the Prophet: “O Messenger! Convey what has been sent down to you from your Lord. If you do not do this, you will not convey His message. Allah will protect you from the people. Indeed, Allah does not instruct the straight path of unbelieving people” (Maida-67).
After the message of the above verse, the Prophet ordered the caravan to halt. After performing the collective zohr prayer, the Prophet ascended the pulpit built from camel palanquins and delivered a sermon.
His Eminence reminded that he bequeaths two values to the mind – the Koran and his family. It is the duty of Muslims to respect these two values and not deviate from them.
Then the prophet raised the hand of Ali ibn Abu Talib, who was standing next to him, and said: “Allah is my patron, and I am the patron of the believers and worthy to show them more than themselves. Whose patron I am, so is Ali the patron.”
The Prophet repeated this suggestion three times, and then said: “O Allah, be a friend to Ali, an enemy to his enemies! Love those who love Ali, be enemies with those who hate him! Help those who help Ali, turn away from those who turn away from him! O people! Convey what you hear to those who are not here!
Before the people dispersed, this verse was sent: “This day I have perfected your religion for you, completed My mercy upon you, and approved Islam for you as a religion” (Maida-3).
