Amr bin Maymun (may Allah have mercy on him) narrates from Abdullah (may Allah be pleased with him): We were forty men with the Messenger of Allah (peace and blessings be upon him) in a tent. He (peace and blessings be upon him) said: "Would you be pleased to be a quarter of the people of Paradise?" They said: Yes! Then he (peace and blessings be upon him) said: "Would you be pleased to be a third of the people of Paradise?" They said: Yes. He (peace and blessings be upon him) said: "By Allah, in Whose Hand is my soul, I hope that you will be half of the people of Paradise. That is because none but a Muslim soul will enter Paradise, and compared with the people of shirk you are like a white hair on the hide of a black bull, or like a black hair on the hide of a red bull."
