It is narrated from Sayyiduna Mu'adh that the Prophet (peace and blessings be upon him) said: The Muslim Ummah will remain steadfast on the Shari'ah until three things prevail: knowledge will be taken away, illegitimate children will become numerous, and the dominance of the "Saqaaroon" will occur. People asked: O Messenger of Allah! What is meant by "Saqaaroon"? The Prophet (peace and blessings be upon him) said: They are the people who will be in the last era, and their mutual meetings will be filled with cursing and blaming each other instead of greeting with peace.
