It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "How will you feel when a quarter of the people of Paradise are yours, and the remaining three quarters belong to all other people?" The Companions said: "Allah and His Messenger know best." He (peace and blessings be upon him) said: "How will you feel when a third of the people of Paradise are yours?" They said: "That is more." He (peace and blessings be upon him) said: "How will you feel when half are yours?" They said: "That is even more." Then the Messenger of Allah (peace and blessings be upon him) said: "The people of Paradise will be one hundred and twenty rows, of which eighty rows will be from you."
