Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "The first things to be taken away from this Ummah will be modesty and trustworthiness, and the last thing to remain will be prayer. The narrator says: I think he also said: Some people will pray, yet they will have no share (in the Hereafter)."
Abu Ya'la recorded it. Its chain contains Ash'ath bin Barraz, who is matruk (abandoned). A statement of Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) on this subject will also come in the subsequent chapter.
