Well, you conveniently left out that for every 1 man their will be 50 women.
That doesn’t apply in our current state.
You know a single world war can easily make that the case which is something we seem to be on the verge of right now any day. Plus many ahadeeth admittedly on the weaker side mention a great war will happen before imam mahdi so this ww3 could be it.
Plus there are numerous ways to interpret 1 to 50.
Maybe slavery will become internationally lawful and men will be taking there spoils of war resulting in men having up to 50 women in there care
Who knows
And I don't get how that affects the first part of the hadeeth since women will go out of there way to join him resulting in men having to chain them down that's not a number issue it's a mental/ideological issue. Dajjal will sell them dreams that will attract them to him.
