2. A number of our people have narrated from Ahmad ibn abu ‘Abd Allah from his father from ‘Amr ibn Ibrahim from Khalaf ibn Hammad from Harun ibn al-Jahm from al-Arqat who has said the following: “Abu ‘Abd Allah (a.s.), once said to me, ‘You must not roam around in market places and you must not perform small tasks personally; it is not proper for a Muslim man of good position and religion to buy small things personally, except three kinds of items, in which case a person of good position and religion should personally perform, such as real estate, slaves and camels.’”

1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Mu’ammar ibn Khallad who has said the following: “I heard abu al-Hassan (a.s.), saying, ‘Once a man came to Ja‘far (a.s.), as if giving him good advice; he said, ‘O abu ‘Abd Allah, Alayhi al-Salam, why have you made the properties in scattered pieces? Had they been in one piece, more profit with fewer expenses could have been made? Abu ‘Abd Allah, Alayhi al-Salam, replied, ‘I have kept them scattered so that if losses affect one piece, others remain unaffected, but a bag keeps all of them together (vulnerable to losses).”’

Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from the one whom he has mentioned (in his book) from Zurarah from Abu ‘Abdillah (AS) who said, "The most difficult property to protect is of the silent kind (gold and silver).’ I then asked, ‘What should one do about it?’ He (the Imam) replied, ‘One should keep them inside walls, a garden or a house.’"
