3. Ali has narrated from his father Muhammad ibn ‘Isma’il has narrated from al-Fadl ibn Shadhan all from Ibn Abi ‘Umayr from Hisham ibn al-Hakam who has said the following: “About the case of a man who buys certain goods with deferred payment for an appointed time, abu Ja‘far (a.s.), has said, ‘He cannot buy it in the manner of Murabahah (capital plus profit) without deferment for an appointed time which is agreed upon; and if he sells in the manner of Murabahah (capital plus profit) without informing the party, then the one who has bought is entitled for a deferment of similar duration.’”

4. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Muhammad ibn ‘Isma’il from Mansur ibn Yunus from Shu’ayb ibn al-Haddad from Bashshar ibn Yasar who has said the following: “This is concerning my question before abu ‘Abd Allah (a.s.), about the case of a man who sells goods on credit with deferred payment, then buys them from the party to whom he has sold. He (the Imam) said, ‘It is not unlawful.’ I then asked, ‘Can I buy my own goods?’ He (the Imam) said, ‘It is not your property, your cow or your sheep.’” Abu Ali al-Ash’ariy has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan from Shu’ayb al- Haddad from Bashshar ibn Yasar from abu ‘Abd Allah (a.s.), a similar Hadith.

1. A number of our people have narrated from Sahl ibn Ziyad from ibn Mahbub from ibn Ri’ab who has said the following: “I once asked abu al-Hassan, Musa (a.s.), about the case of a man who is of my relatives who has left behind small children, slave-boys and slave-girls, and has not made any will. ‘What do you say about one who buys from them a slave-girl for a mother of one’s child and what do you say about selling them?’ He (the Imam) said, ‘If they have a guardian he looks after their affairs, sells for them, and looks after them, he will receive his reward from Allah.’ I then asked, ‘What do you say about one who buys from them a slave-girl to make her mother of his child.’ He (the Imam) said, ‘It is not unlawful if their guardian sells her for them who supervises for them in matters of their interest and they cannot revoke what the guardian has done to protect their interest.’”
