all over the tanach you will see jews arguing with HaShem
and then they are accepted back by Him because of his mercy
and it was already predicted in the Torah this will happen
that doesnt mean he will send and replace his nation
he will only replace them with their children so they can fill in their shoes
if you read the Torah, it says Mosha Rabbeinu asks who is for Allah come with me who is for their old ways will die
i think only a few of each tribe went
the rest didnt want to go until Mosha Rabbeinu thought them well
all those curses in the quran already happened on us and still are occuring
look in the Torah how many curses HaShem bestowed on us
