(60) باب بَيْعِ مَا لَيْسَ عِنْدَ الْبَائِعِ
It was narrated that Hakim bin Hizam said:
"I asked the Prophet "O Messenger of Allah, a man may come to me and ask me to sell him something that I do not have. Can I sell it to him then go and buy it from the market?' He said: 'Do not sell what you do not have.'''
