Bukhari

Hadith Commentary:
(1)
In a narration of Sahih Bukhari regarding the people of Qalib, the Messenger of Allah (sallallahu alayhi wa sallam) said:
"Indeed, these dead now hear what I say to them."
However, Aisha (radi Allahu anha) said that the Messenger of Allah (sallallahu alayhi wa sallam) did not say this, rather he said: "Now they have come to know that what I used to say was the truth." Then she recited the noble verse:
"You cannot make the dead hear."
(Sahih al-Bukhari, al-Maghazi, Hadith: 3980)

Imam Bukhari (rahimahullah) has included the hadith narrated from Ibn Umar (radi Allahu anhu), and then the opposing hadith narrated from Aisha (radi Allahu anha), under the chapter of the punishment of the grave, because when it has been established that the people of Qalib heard the words and rebuke of the Messenger of Allah (sallallahu alayhi wa sallam) with their ears, it means that the perception of punishment through the rest of the senses is also established.
And he (sallallahu alayhi wa sallam) spoke to them at the time when the angels were questioning them, and at that time, the return of the soul (i‘adah al-ruh) had also occurred in them.
And during the questioning, they are also punished. On this basis, reconciliation between these two hadiths is also possible: that the hadith narrated from Abdullah ibn Umar (radi Allahu anhu) means that he (sallallahu alayhi wa sallam) spoke to them at the time when the angels were questioning them.
And the denial by Aisha (radi Allahu anha) is to be understood as referring to a time other than the questioning, i.e., at the time of questioning, both hearing (sama‘) and knowledge (‘ilm) are established for the disbelievers of Quraysh, and at times other than the questioning, only knowledge is established but not hearing.
(Fath al-Bari: 3/299)
And Allah knows best.

The issue of the hearing of the dead (sama‘ al-mawta) will be discussed in the Book of Maghazi (Hadith: 3976).
