1. A number of our people have narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa’id from Fadalah ibn Ayyub from Kulayb al-Asadiy who has said the following: “I once asked abu ‘ Abd Allah, ‘Alayhi al-Salam, about the day of al-Nahr (slaughtering the offering, 10th of Dhu al-Hajjah). He (the Imam) said, ‘It is three days in Mina’, but in the cities, it is only one Day.”
