Arabic (Original)
حَدَّثَنَا هُشَيْمُ بْنُ بَشِيرٍ عَنْ أَبِي بِشْرٍ جَعْفَرِ بْنِ إِيَاسٍ عَنْ يُوسُفَ بْنِ مَاهَكَ عَنْ حَكِيمِ بْنِ حِزَامٍ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ يَأْتِينِي الرَّجُلُ يَسْأَلُنِي الْبَيْعَ لَيْسَ عِنْدِي مَا أَبِيعُهُ ثُمَّ أَبِيعُهُ مِنْ السُّوقِ فَقَالَ لَا تَبِعْ مَا لَيْسَ عِنْدَكَ.
English Translation
Hushaym ibn Bashir told us, from Abu Bishr, Ja'far ibn Iyas, from Yusuf ibn Mahak, from Hakim ibn Hizam, who said: I said, "O Messenger of Allah, a man comes to me asking me to sell him something I do not have with me, and then I go and buy it for him from the market; [is that permitted]?" He said, "Do not sell what is not with you."
