This minaret, which is on the left side of the Umayyad Mosque is also known as the Jesus minaret. It is from here that Hazrat Isa (upon him be peace) will descend back to earth towards the end of time.
Muslims believe that Isa (upon him be peace) did not die on the cross but Allah (Glorified and Exalted is He) raised him to heaven and he will return one day to defeat the Dajjal (Anti-Christ). According to a Hadith, he is on the second heaven. The Prophet (peace and blessings of Allah be on him) mentioned, “During the Me’raj (Ascension), I met Isa (upon him be peace) on the second heaven. I found him of medium stature, reddish white. His body was so clean and clear, that it appeared as though he had just performed ghusal (ablution, cleansing of the entire body) and come.” In another Hadith, the Prophet (peace and blessings of Allah be on him) mentioned to the Jews that, ” Hadhrat Isa (upon him be peace) is not dead, he will most surely return to you before Qiyamat (the Day of Judgement).”
The physical features of Isa (upon him be peace): He will resemble the famous sahabi Urwa bin Masoodi (may Allah be pleased with him). He will be of average height and red and white in colour. His hair will be spread to the shoulders, straight, neat and shining as after a bath. On bending his head, it will seem as if pearls are falling. He will have armour on his body. He will be wearing two pieces of cloth light yellow in colour.
He will descend on a Jamaat (group) that will be righteous at the time and comprising of 800 men and 400 women. The people will be preparing for war at the time against Dajjal. It will be time for Fajr prayers, and Imam Mahdi will be the Amir (leader) of the Muslims. From the darkness of the dawn, a sound will suddenly be heard that “one who listens to your pleas has come” – the righteous people will look everywhere and their eyes will fall on Isa (upon him be peace). Briefly, at the time of Fajr, Isa (upon him be peace) will descend. When descending, Isa (upon him be peace)’s hands will be on the shoulders of two angels (according to another source (Kab Abrar), a cloud will carry him). On their insistence Isa (upon him be peace) will introduce himself. He will inquire about their enthusiasm and thoughts on Jihad against Dajjal. Isa (upon him be peace) will descend on the eastern side near the minaret in Damascus (or in Baitul-Muqaddus according to another narration). At the time Imam Mahdi will have proceeded forward to lead the Fajr Salaat. The Iqamat of the Salaat will already have been recited and Imam Mahdi will call Isa (upon him be peace) for Imamat (to lead the prayer), but he (Isa (upon him be peace)) will instead tell Imam Mahdi to lead the prayer since the Iqamat of that Salaat has already been said for him. Thus Imam Mahdi will lead the prayer, and Isa (upon him be peace) will follow him. After the ruku, he will make this statement: “Allah has killed Dajjal and the Muslims have appeared.”
Isa (upon him be peace) will subsequently kill Dajjal and a great era of peace and harmony will come to the world. Isa (upon him be peace) will marry and have children and will live for 19 years after his marriage. He will then pass away and be buried next to the Prophet (peace and blessings of Allah be on him) in Majid-e-Nabwi, Madinah.
