What is your stance on the authenticity of a video showing a young man being tortured in his grave approximately 3 hours after his burial and exhumation?

The torment and bliss of the grave are established by the texts of revelation from the Qur’an and Sunnah. And Allah, Exalted be He, may show whomever He wills of His servants something of what occurs in the grave. This matter, if true, is among the proofs of the truthfulness of the Prophet’s prophethood, peace and blessings be upon him. And if false, the texts of revelation are sufficient to prove the torment and bliss of the grave. A Muslim should not preoccupy himself with such matters but rather turn to what benefits him in his religion and worldly life and his salvation from the torment of the grave. Furthermore, it is not permissible to exhume a grave after burial except for a legitimate religious benefit.
