This is what they said: that the Prophet ﷺ, when he addressed the people of Badr, those who were killed, the dead of Badr who were in the well.
He said: You do not hear better than they do, you do not hear better than them, okay? So they said this was specific to the Prophet.
A special quality for the Prophet ﷺ, and as for hearing in the graves, the basic principle is that.
The people in the graves do not hear, this is the basic principle, this is the evidence for those who said so, yes. And Allah knows best, and may Allah send prayers and peace upon our Prophet Muhammad, may Allah reward you with good.
