2. Ali ibn Ibrahim has narrated from his father and Muhammad ibn ‘Isma‘il has narrated from al-Fadl ibn Shadhan, all from Ibn Abi ‘Umayr from Mu‘awiyah ibn ‘Ammar, from Abu 'Abdillah

regarding the words of Allah, most Majestic and Glorious, ‘The months of al-Hajj are well-known, so those who owe the obligation of al-Hajj in these months...’ (2:197) He has said that Talbiyah, marking the offering, and leading the offering animal are obligations. Whichever is done the duty of al-Hajj is complete. Al-Hajj is not performed except in the months that Allah, most Majestic and Glorious, has called ‘well-known months’ which are Shawwal, Dhu al-Qa’dah and Dhu al-Hijjah.’”
