He said: They would be on the Sirat.

´It was narrated that ‘Aishah said:` “I asked the Messenger of Allah (ﷺ): “On the Day when the earth will be changed to another earth and so will be the heavens.” [14:48] – where will the people be on that Day?’ He said: ‘On the Sirat (the Bridge across Hell-fire).’”

Benefits and Issues: ➊ The Bridge of Sirat (al-Sirat) is also one of the stages of the Day of Resurrection.
➋ This bridge will be over Hell (Jahannam), and all people will pass over it. Righteous believers will cross it with ease. The more sinful believers and all disbelievers will fall into Hell. After that, sinful believers will come out of Hell through the intercession of the Prophets and righteous people. Those with fewer sins will come out first, and others later. In the end, only the disbelievers will remain in Hell.
