9. Ahmad ibn Muhammad has narrated from ibn abu Nasr from ‘Abd al-Karim from abu Basir who has said the following
“I once asked one of the two Imam, (abu Ja’far or abu ‘Abd Allah), ‘Alayhim al-Salam, about a man for al-Tamattu‘ (advantageous) who cannot find an offering animal until the day for departure when he finds enough funds to buy a sheep, should he slaughter or fast? He (the Imam) said, ‘He must fast; the days for slaughtering have passed.’”
