Sunan Tirmidhi

Narrated by Abdullah ibn Abbas: “One of the companions of the Prophet [Muhammad] set up a tent on a grave while not aware that it was a grave. The man heard the person within the grave reciting Surat Al-Mulk until it was completed. So the man came to the Nabi (SAWS) and informed him of what occurred. The Nabi (SAWS) said, “It is a prevention! It is a salvation saving one from the punishment of the grave!” —— [Abu Isa Tirmidhi said:] This Hadith is [Hasan] Gharib from this route, and there is something on this topic from Abu Hurairah.
