2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Al-Husayn ibn Muhammad from Dawud al-Riqqiy who has said the following: “I once asked abu ‘Abd Allah , about a man who owes one badanah as obligatory ransom. He (the Imam) said, ‘If he cannot find one badanah, then it is seven sheep; and if he cannot afford then he must fast for eighteen days.’”
