What is the ruling on fasting for three days during Hajj and seven days after returning from Hajj for the one performing tamattu' in place of the sacrificial animal?

Question:
What is the ruling on fasting for three days during Hajj and seven days after returning from Hajj for the one performing tamattu' in place of the sacrificial animal, and on which days are the three days to be fasted? Is it after the Day of Sacrifice?

Answer:
Fasting is obligatory for the one who is unable to provide the sacrificial animal; he must fast. Ten days: three during Hajj and seven after his return. These three days are to be fasted before Hajj, before 'Arafah. He fasts them if he knows that he is unable and has no sacrificial animal; he fasts them before 'Arafah. As for the one who hopes to provide the sacrifice, having the means, but then his money is lost and it does not become easy for him when the festival arrives, he fasts three days, specifically the days of Tashriq. It is not permissible to fast on these days except for this reason, or for the inability to perform the Hajj of tamattu' alone. As for anything else, it is not permissible except fasting on the days of Tashriq, because they are days of festival, days of eating, drinking, and remembering Allah. However, there is a specific dispensation for the one who is unable to provide the sacrificial animal for tamattu' to fast these three days in place of the sacrifice, and seven days when he returns to his home. He does not fast on 'Arafah; on 'Arafah he breaks his fast, just as the Prophet (peace and blessings be upon him) broke his fast and forbade fasting on it. So if he wants to fast the three days, he brings them forward before 'Arafah, so that the day of 'Arafah he is not fasting with the Muslims.
