Narrated Ayyub: 'Amr bin Shu'aib narrated to us, saying: My father narrated to me from his father' until he mentioned 'Abdullah bin 'Amr: "The Messenger of Allah (ﷺ) said: 'It is not lawful to lend and sell, nor two conditions in a sale, nor to profit from what is not possessed, nor to sell what one does not have.'" [Abu 'Eisa said:] This Hadith is Hasan Sahih. [Abu 'Eisa said:] The Hadith of Hakim bin Hizam is a Hasan Hadith, it has been reported from him through other routes. Ayyub As-Sakhtiyani and Abu Bishr report from Yusuf bin Mahak, from Hakim bin Hizam. [Abu 'Eisa said:] 'Awf and Hisham bin Hassan reported this Hadith from Ibn Sirin, from Hakim bin Hizam from the Prophet (ﷺ). And this is a Mursal Hadith. Ibn Sirin only reported it from Ayyub As-Sikhtiyani from Yusuf bin Mahak, from Hakim bin Hizam like this.
