Allah, does not state its gonna happen tomorrow. And you trying to bring in ahadith into the picture shows you dont know anything about ahadith. in ahadith, what are the signs of the last day which is "near"? And what have you seen already? You say that Mahdi came, and Jesus came, then who is the Dajjal? Do you even know what ahadith speaks about? You have no clue. You are just blindly following what ever cherry picked ahadith and cherry picked verses of the Qur'an taught to you by whoever.
Please do some research.
According to hadiths (Shia) Imam Mahdi (a) and Isa (a) are going to kill the Dajjal, if both hadiths are true it means they going double team him and kill him at the same time. According to Shiite hadiths, Satan was not given respite to day of judgment but rather the known time which is the rising of the Qaim (a).
To me it makes sense, because Dajjal is Abu Lahab of the time, the Gog, the one who Satan chooses as his Qareen, whether he is hidden (this leader) or manifest, but to put an end to Dajjal, you have to after he is dead, put at end to Satan so no more Qareen he will be to anyone.
But since Quran to me doesn't say anything clearly to me in this regard, except by that we wish the hands of Abu Lahab (his influence) to be cut off and destroyed in Surah Abu Lahab, I don't know at the end. Not saying Quran doesn't say one way or the other, but I don't know.
What Quran does say is that near the end times, Gog and Magog are going hold every high place and will fall from that. To me this means they have the positions of influence and authority right now, but all that they will fall from. At that moment, the hour is closer, since the promises to an extent are done. Then final test is how grateful we are to God and Mahdi (a) and Isa (a) and other ones like Elyas (a) and the believers who helped in all that, and how long justice remains after with Imam Mahdi (a) ruling and Isa (a) ruling too as a vizier (2nd in Command).
They will be exposed and opened up (Gog and Magog) and people will see clearly who were the killers of Imam Hussain (a) and who would repeat that crime if they can all over again.
The devils will also be killed inshallah by spiritual swords.
