٦- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ هِشَامِ بْنِ الْحَكَمِ قَالَ كُنْتُ أَبِيعُ السَّابِرِيَّ فِي الظِّلالِ فَمَرَّ بِي أَبُو الْحَسَنِ مُوسَى (عَلَيْهِ السَّلام) فَقَالَ لِي يَا هِشَامُ إِنَّ الْبَيْعَ فِي الظِّلِّ غِشٌّ وَإِنَّ الْغِشَّ لا يَحِلُّ.
6. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hisham ibn al-Hakam who has said the following: “Once when I was selling al-Sabiriy (a certain kind of fabric) in the shade, abu al-Hassan , passed by and said to me, ‘O Hisham, selling in shade is cheating and cheating is not lawful.’”
