Musnad Ahmad 26:432

Yahya ibn Adam narrated to us, Bashir Abu Isma'il narrated to us, from Sayyar Abu al-Hakam, from Tariq, from Abdullah, he said to him: "O Abu Abd al-Rahman, a man greeting you, and you say: 'Allah and His Messenger have spoken the truth'?" He said: He said, the Messenger of Allah (peace and blessings of Allah be upon him) said: "Before the Hour, there will be the greeting of the elite, and trade will spread until the woman helps her husband in trade, and ties of kinship will be severed."
