Mustadrak al-Hakim — Hadith 8811

It is narrated from Kharijah bin al-Salt al-Burjumi: I entered the mosque with Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him), and the people were in the state of bowing (ruku'). So he (Abdullah) also bowed. Meanwhile a man passed by and greeted him, and Abdullah said: "Allah and His Messenger have spoken the truth." Then he reached the row. When he had finished (the prayer), I asked him about his saying "Allah and His Messenger have spoken the truth," and he said: It used to be said (on behalf of the Messenger of Allah (peace and blessings be upon him)): "The Hour will not be established until the mosques are taken as roads (thoroughfares), until a man greets only those he knows, until a woman engages in trade together with her husband, and until horses and women become expensive and then (so) cheap that they will not become expensive again until the Day of Resurrection."
This hadith has a sahih (authentic) chain of narration, but the two Shaykhs did not record it.
