Zuhayr narrated to us, Abdullah bin Yazid narrated to us, Sa'id bin Abi Ayyub narrated to us, he said: I heard Darraj Abu al-Samh say: I heard Abu al-Haytham say: I heard Abu Sa'id al-Khudri say: The disbeliever will have ninety-nine dragons empowered over him in his grave; they will bite him and sting him until the Hour is established. If one of those dragons were to blow upon the earth, no greenery would grow.
