question #3 Sahih al-Bukhari 4026, Book 64, Hadith 75 : What can be inferred about the belief in the awareness of the deceased from the Prophet’s statement during the Battle of Badr?

These were the battles of Allah’s Messenger (ﷺ) (which he fought), and while mentioning (the Badr battle) he
said, “While the corpses of the pagans were being thrown into the well, Allah’s Messenger (ﷺ) said (to them),
‘Have you found what your Lord promised true?” `Abdullah said, “Some of the Prophet’s companions
said, “O Allah’s Messenger (ﷺ)! You are addressing dead people.’ Allah’s Messenger (ﷺ) replied, ‘You do not hear
what I am saying, better than they.’ The total number of Muslim fighters from Quraish who fought in
the battle of Badr and were given their share of the booty, were 81 men.” Az-Zubair said, “When their
shares were distributed, their number was 101 men. But Allah knows it better.”
