In his book, Siyar A‘laam An-Nubalaa’ (11/238), Ath-Thahabi said that during the ordeal of Imaam Ahmad it was said to him, “O Abu ‘Abdullaah! Do you not see that falsehood is being victorious over the truth?”
“No. The victory of falsehood over truth is when the hearts change from guidance to error but our hearts are still adhering to the truth.”
How badly are we in need for this accurate criterion that shows the reality of the victory of falsehood over truth, especially in this age when many hearts have been affected by trials of doubtful issues and desires, we seek refuge with Allah The Almighty from them.
