You are confusing the two. Nowhere has Prophet Muhammad (saww) claimed about the knowledge of when Qayamat will come and no muslim will ever claim as such.
These signs of Qayamat are without a doubt revealed to Prophet Muhammad (saww) from Allah to warn us of Dajjal and the day of judgment. To tell us of the coming of Prophet Isa(a.s) are you going to deny that too because the coming of Isa(a.s) is in Holy Quran.
Prophet Muhammad (saww) after Miraj told us about the hell and heaven and what will happen. Are you going to deny that too? It is the knowledge of the unseen.
Read again. Nowhere has Prophet Muhammad (saww) claimed about the Hour time, it is blasphemy to think that. He(saww) has said and done what Allah has willed.
It is a sign of qayamah that people will reject the ahadiths!!.
The Hour can come anytime, surely the signs have come true. We don't know who the dajjal is, who the yajooj majooj are, maybe they've already come in the past. Maybe Isa(as) has come too and gone. These signs don't tell you when the Hour will come.
Your imagining dajjal to be some monster but we don't know what he will be like and perhaps he is just figurative. Maybe the dajjal is America who is promising people heaven in the form of fornication, homosexuality, mockery of religion and hell in the form of persecution if you practise Islam.
Don't be so arrogant. We are all ignorant and only the righteous will know who Dajjal is. Maybe we aren't the righteous and are the condemned ones and haven't seen dajjal and prophet isa(as).
Don't reject the hadiths just because you're ignorant. The video shows how the prophecies have come true and it proves that The Hour is inching closer, could be any second or day. Nowhere does it claim when it will be.
مندرجہ ذیل آیات میں اللہ کا رسولﷺ کو حکم ہے کے جو لوگ آپ سے قیامت کے بارے میں پوچھتے ہیں۔اُن کو بتا دیں کہ آپ کچھ نہیں جانتے اور اِس کا علم صرف اللہ تعالٰی کو ہی ہے۔ کون سا ایسا مسلمان ہے جو یہ سوچ بھی سکتا ہے کہ اِتنے واضح حکم کے باوجودآپ ﷺقیامت کی نشانیاں بتائیں گے؟ آیت میں واضح طور پر کہا گیا ہے کہ قیامت اچانک آئے گی تو کسی نشانی کا سوال ہی پیدا نہیں ہوتا۔ جو لوگ قیامت کی نشانیوں والی کہانیاں آپﷺ سے منسوب کرتے ہیں وہ رسولﷺ پر بہتان لگا رہے ہیں۔جس کا واحدمقصد اپنے بڑوں کے عقیدوں کا دفاع ہے چاہے وہ قرآن کے منکر ہی کیوں نہ ہو جائیں۔
