7. A number of our people have narrated from Sahl ibn Ziyad Ahmad ibn Muhammad from Ahmad ibn Muhammad from ibn Mahbub from abu Hamzah who has said the following:

“I once asked abu Ja‘far , about the words of Ali , about al-Rahn (security deposit and mortgage) ‘both sides return the extra’. He (the Imam) said, ‘Ali , indeed would say it.’ I then asked, ‘How both sides return?’ He (the Imam) said, ‘If what is mortgaged is more than the amount the mortgage has provided and it is destroyed, the mortgagee returns the difference to mortgager; if it is not equal the mortgager returns the difference to the mortgagee.’ He (the Imam) said, ‘This is how Ali, Alayhi al-Salam, would say about animals and other goods.’”
