Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The Hour will not be established until Allah Almighty takes away the best people from among the inhabitants of the earth, and (only) the wicked remain on it, who will not recognise any good as good nor reject any evil as evil."
Ahmad recorded it both marfu' (attributed to the Prophet) and mawquf (stopping at the Companion), and the narrators of both are the narrators of the Sahih.
