2. Ahmad ibn Muhammad ibn abu Nasr has narrated from ‘Abd al-Karim ibn ‘Amr from Zurarah who has said the following: “One of the two Imam, (abu Ja’far or abu ‘Abd Allah), ‘Alayhim al-Salam, has said, ‘One who cannot find an offering and likes to fast the three days during the first ten days, it is not an offense for him to do so.”

3. Ali ibn Ibrahim has narrated from his father and Muhammad ibn ‘Isma‘il has narrated from al-Fadl ibn Shadhan from Safwan ibn Yahya and Ibn Abi ‘Umayr from Mu‘awiyah ibn ‘Ammar who has said the following: “I once asked abu ‘Abd Allah (a.s.), about a man who is for al-Tamattu‘ (advantageous) and does not find offering-animal. He (the Imam) said, ‘He is required to fast three days in al-Hajj, one day before al-Tarwiyah (eight of Dhu al-Hajj ah), on the day of al-Tarwiyah and on the day of ‘Arafah.’ I then asked, ‘What is the rule if he misses it?’ He (the Imam) said, ‘He can eat food before dawn on the day of al-Hasabah, fast that day and two more days thereafter.’ I then asked, if camel man does not wait for him, can he fast on the way?’ He (the Imam) said, ‘Yes, if he likes he can fast on the way or when he returns home to his family.’”
