Hadith record

It is narrated from the Imams (as): "If the Mutamatti' (pilgrim performing Hajj Tamattu') finds the sacrificial animal but cannot afford its price, he must fast for three days during Hajj—one day before the Day of Tarwiyah, the Day of Tarwiyah itself, and the Day of Arafah—and seven days when he returns to his family, as stated in the Quran: 'That is ten complete days' (Surah Al-Baqarah 2:196), as a compensation for the hady (sacrificial animal). If he misses fasting these three days, he should partake in the pre-dawn meal on the night of al-Hasbah (the night of departure) and begin fasting in the morning, then complete the fast for two additional days afterward. If he misses fasting these three days until he departs and cannot stay, he may fast the three days while on the journey if he wishes, or he may fast all ten days when he reaches his family. He should separate the three days from the seven by one day, although fasting them consecutively is also permissible. However, he is not allowed to fast during the Days of Tashriq, for the Prophet (peace and blessings be upon him and his family) sent Budayl ibn Warqa' al-Khuza'i on a gray camel to go through the tents and announce to the people in Mina: 'Beware, do not fast during these days, for they are days of eating, drinking, and marital relations.' If someone is unaware of the obligation to fast the three days during Hajj, he may fast them in Mecca if his camel driver stays, and if not, he may fast them on the way or in Medina if he wishes. When he returns to his family, he must fast the seven days. If he dies before returning to his family and fasting the seven days, there is no obligation upon his guardian to make them up."
