Is what is narrated about seeing "the Brave Bald Man" or what the deceased is foretold in his grave true?

The torment of the grave is established by Quranic verses and Prophetic traditions, and it is the doctrine of the People of the Sunnah (Ahl al-Sunnah). Its exact nature is a matter of the unseen, in which we must restrict ourselves to what has been mentioned in the Quran and Sunnah. There are narrations about the "brave bald one" (al-Shuja' al-Aqra') on the Day of Resurrection and regarding those who withhold zakat, but what is mentioned therein as being part of the torment of the grave has not been authenticated in its chain of transmission. There is no religious or rational impediment for Allah Almighty to reveal the torment of the grave, or some of it, to some of His servants, especially the righteous. Indeed, it has been narrated from Ibn Umar (may Allah be pleased with both of them) that he witnessed things from the torment of the grave, but Ibn Abd al-Barr cited this hadith for consideration and not for argumentation due to the presence of unknown narrators within it. Therefore, there is no impediment for some people, especially the righteous, to witness things from the torment of the grave.
