With this chain also, it is narrated from Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "My Ummah will have five groups, and each group will last for forty years. My group and that of my Companions is the group of people of knowledge and people of faith, and the second group, from forty to eighty, is the group of people of righteousness and people of piety." Then the narrator mentioned a hadith with the same meaning as the previous hadith.
