It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that when this verse was revealed: "A multitude from the former peoples and a few from the later peoples," this was very hard on the Muslims (that only a few from the latter people would be destined for Paradise). Then this verse was revealed: that there will be a group from the former and a group from the latter. And the Noble Prophet (peace and blessings be upon him) said: "You will be a third of all the people of Paradise, rather half, and in the remaining half, they will be your partners."
