It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "On the Day of Resurrection, Allah Almighty will send a caller to proclaim: O Adam! Allah commands you to send forth from your descendants those destined for Hellfire." He will ask: "O Lord! How many out of how many?" It will be said: "From every hundred, ninety-nine." Upon hearing this, a man said: "O Messenger of Allah (peace and blessings be upon him)! Then who among us will be saved after that?" The Prophet (peace and blessings be upon him) said: "Do you know what your proportion will be among the people? You will be like the white spot on the hump of a black camel."
