The Messenger of Allah said: 'One of the portents of the Hour will be that wealth becomes widespread and abundant, and trade will become widespread, but knowledge will disappear. A man will try to sell something and will say: No, not until I consult the merchant of banu so and so: and People will look throughout a vast area for a scribe and will not find one. (Sahih )

:Telah mengabarkan kepada kami Qutaibah bin Sa'id ia berkata; telah menceritakan kepada kami Sufyan dari Az Zuhri dari Salim dari ayahnya bahwa Nabi shallallahu 'alaihi wasallam melarang dari menjual buah dengan kurma. Ibnu Umar berkata; telah menceritakan kepadaku Zaid bin Tsabit bahwa Rasulullah shallallahu 'alaihi wasallam memberikan keringanan dalam hal 'araya.
