When Nabi Isa (‘alaihis salaam) returns to the world, the Mahdi (radhiyallahu ‘anhu) will be the leader guiding the Muslims. The Mahdi (radhiyallahu ‘anhu) will say to Nabi Isa (‘alaihis salaam) that he should lead the Muslims, as he is the Nabi of Allah Ta‘ala. (Ibnu Hibbaan #6812, Fitan li-Nu’aim #1028)
The armies of the Muslims, under the leadership of Nabi Isa (‘alaihis salaam), will then wage war against Dajjaal and his armies. Nabi Isa (‘alaihis salaam) will kill Dajjaal and the Muslims will be victorious in this battle.
Not long thereafter, the Mahdi (radhiyallahu ‘anhu) will pass away and Nabi Isa (‘alaihis salaam) will perform his janaazah salaah. Nabi Isa (‘alaihis salaam) will continue to live in the ummah, practising Islam and guiding people towards Islam. Nabi Isa (‘alaihis salaam) will get married and have children.
After some time passes, Allah Ta‘ala will release the Ya’jooj and Ma’jooj in the world. They will cause corruption and destruction in the world, wherever they go. Thereafter, Allah Ta‘ala will send down a catastrophe upon them which will cause all of them to die.
After the Ya’jooj and Ma’jooj are destroyed by Allah Ta‘ala, Allah Ta‘ala will send down abundant rain, causing crops to grow in abundance and animals to thrive. The people of the earth will be blessed with immense barakah at that time. Due to the barakah, the size of the fruit and crops will also increase. There will also be complete safety, to the extent that people will have no fear of being harmed by the wild and venomous animals. Disunity and fighting will also cease to exist as enmity and hatred will leave the people’s hearts.
Rasulullah (sallallahu ‘alaihi wasallam) said:
Nabi Isa (‘alaihis salaam) will remain in my ummah as a just ruler and fair leader. He will break the cross, slaughter the swine and bring an end to jizyah (the tax levied on non-Muslim citizens in an Islamic state will no longer be levied as everyone will accept Islam). Zakaat will no longer be taken (as everyone will have sufficient wealth), so no zakaat collector will be sent to collect goats or camels. Hatred and enmity for one another will be raised from the world. The sting (and harm) will be removed from every animal that stings (or harms), until a small child will place his hand in the mouth of a snake without it harming him, and a small girl will chase a lion and it will not harm her, and a wolf will remain among goats like a shepherd dog. The earth will be filled with peace, just as a vessel is filled with water. There will be complete unity as only Allah Ta‘ala will be worshipped. War will come to an end and the Quraish will regain leadership. The earth will be like a silver platter, producing crops as it did in the era of Nabi Aadam (‘alaihis salaam), until an entire group of people will eat from one bunch of grapes and will be satiated, and an entire group of people will eat from one pomegranate and will be satiated. (Sunan Ibnu Maajah #4077)
Performing Hajj and Umrah and Visiting the Blessed Grave of Rasulullah (sallallahu ‘alaihi wasallam)
After his descent from the heavens, Nabi Isa (‘alaihis salaam) will perform hajj and umrah. Rasulullah (sallallahu ‘alaihi wasallam) said, “I take an oath by that Being in whose hand lies my life! The son of Maryam (i.e. Nabi Isa [‘alaihis salaam]) will most certainly recite the talbiyah (Labbaik) at the pass of Rowhaa, at the time when he will go to perform hajj or umrah, or he will certainly perform both.” (Saheeh Muslim #1252)
In another Hadith. Rasulullah (sallallahu ‘alaihi wasallam) mentioned, “Qiyaamah will not occur until Isa bin Maryam (‘alaihis salaam), the slave and Rasul of Allah, does not pass by Rowhaa, at the time when he will go to perform hajj or umrah, or Allah Ta‘ala will combine both for him.” (Majma’uz Zawaa’id #9941)
On coming to Madinah Munawwarah, Nabi Isa (‘alaihis salaam) will visit the blessed grave of Rasulullah (sallallahu ‘alaihi wasallam). Rasulullah (sallallahu ‘alaihi wasallam) said, “Isa bin Maryam (‘alaihis salaam) will most certainly descend (to the earth, before Qiyaamah) as a fair ruler and just leader. He will definitely travel through a mountain pass while coming to perform hajj, or umrah, or with the intention of performing both. He will definitely come to my grave and greet me with salaam, and I will reply to his salaam.” (Mustadrak Haakim #4162)
In certain Ahadith, Rasulullah (sallallahu ‘alaihi wasallam) had exhorted the ummah that when they meet Nabi Isa (‘alaihis salaam), then they should convey his salaam to Nabi Isa (‘alaihis salaam). (Majma’uz Zawaa’d #12569)
Being Buried Next to Rasulullah (sallallahu ‘alaihi wasallam)
From the time of his descent, Nabi Isa (‘alaihis salaam) will live in the ummah for the total period of forty-five years. He will then pass away, the Muslims will perform his janaazah salaah and he will be buried next to Rasulullah (sallallahu ‘alaihi wasallam).
Rasulullah (sallallahu ‘alaihi wasallam) said, “Isa bin Maryam (‘alaihis salaam) will descend to the earth. After his descent, he will marry and have children. He will then remain in the world for forty-five years after which he will pass away. He will be buried next to my grave. Hence, (on the Day of Qiyaamah,) I will rise up with him from the same place between Abu Bakr and Umar (radhiyallahu ‘anhuma).” (Mishkaat #5508)
In another Hadith, Hazrat Abdullah bin Salaam (radhiyallahu ‘anhu) reports, “The description of Muhammad (sallallahu ‘alaihi wasallam) is recorded in the Towraah, and it is also recorded in the Towraah that Nabi Isa bin Maryam (‘alaihis salaam) will be buried with him.” (Sunan Tirmizi #3617)
