Hadith 1050
´Abu Marthan Al-Ghanawi narrated that:` The Prophet said: "Do not sit on the graves nor perform Salat towards them."
Hadith 1051
´(Another chain) from Abu Marthad Al-Ghanawi :` from the Prophet, similar (to no. 1050), but it does not contain "From Abu Idris" and this is what is correct.
