Abu Sa’eed Al-Khudri (radiyallaahu anhu) narrated that the Messenger of Allaah (sallal-laahu-alayhi-wasallam) said: Indeed shaytaan said: ”By Your Might O my Lord! I will not cease to misguide your slaves as long as their souls are in their bodies”; The Lord (Allaah) said: ”By My Might and Majesty! I will not cease forgiving them as long as they keep seeking my forgiveness.”
