Musnad Ahmad 33:114

Waki’ narrated to us, from Sufyan, from Ibn al-Munkadir, from Jabir, who said: When I got married, the Prophet (peace and blessings of Allah be upon him) said: "Have you acquired *anmat* (cushions/rugs)?" I said: "Where would we get *anmat* from?" He said: "Verily, they will come to be." And I say to my wife: "Remove your *namat* (cushion/rug) from me," and she says: "Did the Messenger of Allah (peace and blessings of Allah be upon him) not say: 'They will come to be'?"
