11. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn Hadid from Jamil from Zurarah who has said the following:

“I once asked abu Ja‘far , about the case of a man who purchases something from a man and leaves it with him saying, ‘I will come back with payment.’ He (the Imam) said, ‘If he comes back with payment within three days the transaction is valid, otherwise, it is not valid.’”
