They wanna end these Muslims who are threatening, whose preachings are threatening the pilgrimage, the legitimacy of the Quraysh tribe in Mecca. And so they laid siege to the city of Medina. And as a defensive measure, the Muslims in Medina create a trench around the city. And that's why this is called the Battle of the Trench. And once again, according to Islamic tradition, the Muslims are outnumbered three to one. So this is right over here, the Battle of the Trench, in which the Muslims are victorious. And this is a significant blow to the legitimacy, the prestige of the Quraysh tribe.
