7. Abu Ali af-Ash’ariy has narrated from Muhammad ibn ‘Abd af-Jabbar from Safwan ibn Yahya from Yahya af-Arzaq who has said the following: “I once asked abu al-Hassan , about a man for al-Tamattu‘ (advantageous) who has enough funds for the offering animal available but he delays until the evening when prices become high and the funds that he has now are not enough to buy what he could buy earlier in the day. He (the Imam) said, ‘He is required to fast three days after the days of tashriq, 11, 12 and 13.’”
