Jubayr (may Allah have mercy on him) narrates: Sayyiduna Abu Jum'ah al-Ansari (may Allah be pleased with him), the Companion of the Messenger of Allah (peace and blessings be upon him), came to us in Bayt al-Maqdis to pray there, and Raja' bin Haywah (may Allah have mercy on him) was with us that day. When he was leaving, we went out with him to see him off. When we intended to turn back, he said: You have a gift and a right over me, that I narrate to you a hadith which I heard from the Messenger of Allah (peace and blessings be upon him). We said: Narrate it, may Allah have mercy on you. He said: We were with the Messenger of Allah (peace and blessings be upon him), and Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) was with us, the tenth of ten. We said: O Messenger of Allah, is there any people greater in reward than us? We believed in you and followed you. He (peace and blessings be upon him) said: "What could prevent you from that, when the Messenger of Allah (peace and blessings be upon him) is among you and revelation comes to you from the heaven? Yes, there are people to whom a Book will come between two boards; they will believe in it and act upon what is in it. They are greater than you in reward, they are greater than you in reward, they are greater than you in reward."
