Iron talking and the far becoming near at the end of time

Q 1: How correct is the saying: "At the end of time, iron will speak, the far will become near, and slaves will rule or slaves will be emancipated"? Is this a Hadith which was authentically reported from Allah's Messenger (peace be upon him)? Is it a common saying?

A: This saying was not authentically reported from the Prophet (peace be upon him). In this regard, Al-Bukhari, Muslim, and others related on the authority of Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace be upon him) said: "Time will pass rapidly, knowledge will decrease, trials will take place, miserliness will be thrown (in the hearts of the people), (Part No. 2; Page No. 330) and the Harj will increase." They asked, "What is the Harj?" He replied, "(It is) murdering, (it is) murdering." May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
