It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "By the One in whose Hand is my soul! All of you will surely enter Paradise, except the one who refuses (to enter Paradise) and bolts away from Allah the way a camel bolts away."
It was said: "O Messenger of Allah! Who is it that refuses to enter Paradise?" So he (peace and blessings be upon him) said: "Whoever obeys me will enter Paradise, and whoever disobeys me will enter the Fire."
No one narrated this hadith from al-Ala' bin al-Musayyab (may Allah have mercy on him) except Khalaf bin Khalifah (may Allah have mercy on him).
