٦- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ يَحْيَى بْنِ الْحَجَّاجِ عَنْ خَالِدِ بْنِ نَجِيحٍ قَالَ قُلْتُ لأبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) الرَّجُلُ يَجِي‏ءُ فَيَقُولُ اشْتَرِ هَذَا الثَّوْبَ وَأُرْبِحَكَ كَذَا وَكَذَا فَقَالَ أَلَيْسَ إِنْ شَاءَ أَخَذَ وَإِنْ شَاءَ تَرَكَ قُلْتُ بَلَى قَالَ لا بَأْسَ بِهِ إِنَّمَا يُحَلِّلُ الْكَلامُ وَيُحَرِّمُ الْكَلامُ.
6. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Yahya ibn al-Hajjaj from Khalid ibn Najih who has said the following: “I once said to abu ‘Abd Allah , ‘A man comes to me and says, “Buy this cloth and I give you so and so much profit.’” He (the Imam) asked, ‘Can he take or leave it if he so wants?’ I replied, ‘Yes, he can do so.’ He (the Imam) said, ‘It is lawful. It is statements that make it lawful as well as unlawful.’”
