4- حُمَيْدُ بْنُ زِيَادٍ عَنِ الْحَسَنِ بْنِ مُحَمَّدِ بْنِ سَمَاعَةَ عَمَّنْ ذَكَرَهُ عَنْ أَبَانِ بْنِ عُثْمَانَ عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي عَبْدِ اللهِ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَنِ الرَّجُلِ يَشْتَرِي بَيْعاً فِيهِ كَيْلٌ أَوْ وَزْنٌ يُعَيِّرُهُ ثُمَّ يَأْخُذُهُ عَلَى نَحْوِ مَا فِيهِ قَالَ لا بَأْسَ بِهِ.
4. Humayd ibn Ziyad has narrated from al-Hassan ibn Muhammad ibn Sama‘ah from those whom he has mentioned from Aban ibn ‘Uthman from ‘Abd al- Rahman ibn abu ‘Abd Allah who has said the following: “This is concerning my question before abu ‘Abd Allah (a.s.), about the case of a man who buys something which is sold by measure or weight and takes it according to that standard. He (the Imam) said, ‘It is not harmful.’”
