Super curly haircut: Why do people think Muslims don`t believe in Christ when the Quran says differently?

he Mahdi, according to majority Sunni and Shi'ite tradition, will arise at some point before the day of judgement, institute a kingdom of justice, and will in the last days fight alongside the returned Jesus against the Dajjal (Antichrist or false Messiah).

Ithna Ashari Shia sources

He was born in 868 and is still alive.

He has been in 'occultation'-that is, absent from the physical world-since the age of five years

His father is the 11th Shi'a Imam, Hasan al-Askari

His mother is Narjis, a Byzantine princess

Twelver Shia Muslims believe that the Mahdi is the 12th and last of the Shi'a Imams

Muslims identified the Antichrist as a man who will come in the end times, who will command great powers, and will be popular in his heyday but will cause havoc and spread terror around the world. He is called Al Massih Al-Dajjal. Al-Massih refers to Messiah (Arabic ??????;) and Dajjal refers to the fact of being False/Liar.

The Prophet, Allah's apostle said, "No prophet was sent but that he warned his followers against the one-eyed liar (Ad-Dajjal). Beware! He is blind in one eye, and your Lord is not so, and there will be written between his (Ad-Dajjal's) eyes (the word) Kafir (i.e., disbeliever)." (This Hadith is also quoted by Abu Huraira and Ibn 'Abbas). [Hadith - Bukhari 9.245, Narrated Anas]

... He (the Dajjal) will be a young man with twisted, cropped hair, and a blind eye. I compare him with AbdulUzza ibn Qatan. He who among you will survive to see him should recite over him the opening verses of Surah al-Kahf (xviii). He will appear on the way between Syria and Iraq and will spread mischief right and left. O servant of Allah! Adhere (to the path of Truth)... He will come to the people and invite them (to a wrong religion); they will affirm their faith in him and respond to him. He will then give a command to the sky: there will be rainfall upon the Earth and it will grow crops. Then in the evening, their pasturing animals will come to them with their humps very high, their udders full of milk and their flanks distended. He will then come to another people and invite them. But they will reject him so he will go away from them; they will have a drought and nothing will be left with them in the form of wealth. He will then walk through the desert and say to it: Bring forth your treasures. The treasures will come out and gather before him like a swarm of bees. He will then call someone in the flush of youth, strike him with the sword, cut him into two pieces and (make these pieces lie at the distance which is generally between the archer and his target. He will then call (that young man) and he will come forward laughing with his face gleaming (with happiness). It will at this very time that Allah will send Isa (The Christ/Jesus), son of Mary. He will descend at the white minaret on the eastern side of Damascus, wearing two garments lightly dyed with saffron and placing his hands on the wings of two Angels. When he lowers his head, there will fall beads of perspiration from his head, and when he raises it up, beads like pearls will scatter from it. Every non-believer who smells the odour of his body will die and his breath will reach as far as he is able to see. He will then search for him (Dajjal) until he catches hold of him at the gate of Ludd and kills him. Then a people whom Allah had protected will come to Isa, son of Mary, and he will wipe their faces and inform them of their ranks in Paradise... [Hadith - Muslim #7015, Narrated An-Nawwas ibn Sam'an]
