Sayyiduna Abu Sa‘id Khudri (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said:“The entire earth is a place of prostration (mosque) except for graveyards and bathhouses.”(That is, it is not permissible to pray in graveyards and bathhouses.) Imam Darimi (may Allah have mercy on him) was asked: If someone prays in a graveyard, will his prayer be valid? He replied: If he prayed in a place where there was no grave, then the prayer will be valid, and he said: Most narrators have reported this hadith as mursal.
