17. Ali ibn Ibrahim has narrated from his father from certain individuals of his people from al-Husayn ibn al-Mukhtar from abu ‘Usamah from Humran from abu Ja’far who has said the following: “Allah, the Most Majestic, the Most Holy, has an undertaking to try the believers with misfortune just as a man is committed to send gifts to his family in his absence. He holds him (believer) back from the worldly things just as the physicians hold back a patient from certain items of food.”
