Sayyiduna Abu Sa‘id Khudri (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings of Allah be upon him) said: “Ninety-nine serpents are set upon the disbeliever in his grave, which tear him apart and bite him, and this continues until the Day of Resurrection. If even one of those serpents were to blow upon the earth, the earth would never produce vegetation.”
