Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 27
وَ قَالَ أَبُو جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ: "فِي رَجُلٍ أَمَرَهُ نَفَرٌ أَنْ يَبْتَاعَ لَهُمْ بَعِيراً بِوَرِقٍ وَ يَزِيدُونَهُ فَوْقَ ذَلِكَ نَظِرَةً فَابْتَاعَ لَهُمْ بَعِيراً وَ مَعَهُ بَعْضُهُمْ فَمَنَعَهُ أَنْ يَأْخُذَ مِنْهُمْ فَوْقَ وَرِقِهِ نَظِرَةً".
Abu Ja'far Imam Muhammad ibn Ali Al-Baqir عليه السلام said regarding a man who was instructed by a group to buy a camel for them with silver and to charge them extra for deferred payment. He bought the camel for them, and one of them was with him. Imam عليه السلام prohibited him from taking more than the silver amount for the deferred payment.
