Using Proper and Improper Measurements in Business

2. Through the same chain of narrators as the previous one from Ya’qub ibn Yazid from Muhammad ibn Murazim from a man from Ishaq ibn ‘Ammar who has said the following: “Abu ‘Abd Allah عليه السلام, has said, ‘If one uses a balance with the intention to weigh for himself properly ends up weighing heavier for himself, and one who intends to weigh equally, ends up weighing less.’”

3. Through the same chain of narrators as the previous one from al-Hajjal from ‘Ubayd ibn Ishaq who has said the following: “I once said to abu ‘Abd Allah عليه السلام, ‘I own palm trees. Instruct me how to be proper in my giving and taking.’ Abu ‘Abd Allah عليه السلام, said, ‘Keep your intention to maintain it (crop) properly fair; if despite such intention, less proper fairness takes place, you are of those who maintain it properly. On the other hand, if you intended it to be less proper, but maintained it properly, you are of those who maintain it less properly.’”

4. Muhammad ibn Yahya narrated from Ahmad ibn Muhammad ibn Isa, from Ali ibn al-Hakam, from Muthanna al-Hannat, from some of our companions, from Abu Abdillah al-Sadiq عليه السلام, who said: "I said to him, 'A man has the intention of being honest, but when he measures, he does not know how to measure.' He said, 'What do those around him say?' I said, 'They say he does not fulfill (his measures).' He replied, 'This person should not measure.'"

5. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from more than one person who has said the following: “Abu ‘Abd Allah عليه السلام, has said, ‘It is not a proper weighing until a side of balance tilts.’”
