14. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Muhammad ibn ‘Abd Allah ibn Hilal from ‘Uqbah ibn Khalid who has said the following: “I once asked abu ‘Abd Allah (a.s.), about a man for al-Tamattu‘ (advantageous) who does not have anything to buy an animal for offering. He fasts three days in al-Hajj but then it becomes possible for him to buy an animal for offering. Must he buy an animal for offering and slaughter it or leave it alone and fast the remaining seven days when he is back home in his family? He (the Imam) said, ‘He must buy an animal for offering and his fasting is of extra benefit for him.’”

Ali ibn Ibrahim has narrated from his father from in a marfu‘ manner the following: “This is about the words of Allah, most Majestic, most Glorious, ‘If he cannot find (offering) he must fast three days in al-Hajj and seven days when you return and this becomes ten complete.’ (2:196) He (the Imam) (a.s.), said that completing fasting is completing the offering obligation.’”

16. Certain persons of our people have narrated from Muhammad ibn al-Husayn from Ahmad ibn ‘Abd Allah al-Karkhiy who has said the following: “I once asked al-Rida’ (a.s.), about a man for al-Tamattu‘ (advantageous) who arrives but does not have any animal for offering with him; if he can fast before the time to slaughter the offering. He (the Imam) said, ‘He must wait until the day of al-Nahr (slaughtering the offering, 10th of Dhu al- Hajjah); and if he did not find any animal for offering, then he is of ‘those who cannot find’ (2:196) an animal for offering.’” (Fatwa best explains Hadith 3-16 of this Chapter)
