Hadith Commentary:Benefits and Issues: The Messenger of Allah (sallallahu alayhi wa sallam) was a Prophet, and Abu Bakr (radi Allahu anhu) was a martyr, and regarding the rest of the companions, he (sallallahu alayhi wa sallam) foretold their martyrdom. In the following narration, Sa’d ibn Abi Waqqas (radi Allahu anhu) is also counted among the martyrs, because he too is among those regarding whom the Prophet (sallallahu alayhi wa sallam) bore witness to their entry into Paradise.

´Narrated Abu Hurairah [may Allah be pleased with him]:` that the Messenger of Allah (ﷺ) was at Hira, him, Abu Bakr, 'Umar, 'Uthman, 'Ali, Talhah and Az-Zubair (may Allah be pleased with them all), and the boulder (mount Hira) shook. So the Prophet (ﷺ) said: "Be calm, for there is none upon you except a Prophet, or a Siddiq, or a martyr."

Explanation: 1: In Sahih Bukhari, in the Book of the Virtues of the Companions (Chapter: The Merits of Abu Bakr) and (Chapter: The Merits of Uthman), there is mention of "Mount Uhud." According to Hafiz Ibn Hajar rahimahullah: these are two separate incidents. There is no contradiction or conflict in this matter.
