4. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Safwan from Ya’qub ibn Shu’ayb who has said the following: “This is concerning my question before abu ‘Abd Allah, ‘Alayhi al-Salam, about the case of a man who gave impure dirhams as a loan to another man, who then paid him back with better dirhams without compulsion. He (the Imam) said, it is not unlawful and it is from Ali, ‘Alayhi al-Salam.’”

5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from Yunus ibn Ya’qub from abu Maryam who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, whenever owing something to someone would pay back heavier.’”

6. Abu Ali al-Ash’ariy has narrated from Muhammad ibn ‘Abd al-Jabbar and Muhammad ibn ‘Isma’il has narrated from al-Fadl ibn Shadhan from Safwan from ‘Abd al-Rahman ibn al-Hajjaj who has said the following: “This is concerning my question before abu ‘Abd Allah, ‘Alayhi al-Salam, about the case of a man who borrowed from another man dirham and returned with a Mithqal (a certain unit of weight) or borrowed a Mithqal and paid back with dirham. He (the Imam) said, ‘If there is no stipulation it is not unlawful, it is only extra. My father would borrow dirhams of low quality and pay back with dirhams of high quality and say to me, “My son, pay it back to the one from whom I have borrowed.” I would say, “Father, the dirhams you borrowed were of low quality and these are better.” He (the Imam) would say, ‘My son, it is an extra favor. Give it back to him.’”
