did not act as if they had heard about it, and Shaban and Lewis () thus consider this designation improbable. In contrast, Amir-Moezzi writes that the Shia Amini has compiled volumes of Sunni and Shia historical evidence, in support of the Shia interpretation of the Ghadir Khumm. Noting that Abu Bakr () designated Umar () to succeed him, Lalani also suggests that Muhammad did appoint a successor but his choice was ignored by the community. The view of Abbas is similar, and the Shia view is also that the community ignored the designation of Ali. They add that numerical strength cannot be a factor in a tribal community where decisions are made by tribal leaders, and that majority does not imply legitimacy in the Qur'an. Some have instead argued that Muhammad would have made such an important announcement earlier at Hajj, while Abbas views this as criticizing Muhammad's judgement. Sunni commentators also argue that the Verse of Ikmal (5:3) refers to either the establishment of the rites for Hajj during the Farewell Pilgrimage or the closure of Islamic legislation with the revelation of dietary instructions in the remainder of this verse. A criticism of this view, voiced by Tabatabai, is that it ignores the additional injunctions about which were revealed after the Verse of Ikmal by some accounts. Most Sunni scholars meanwhile link the Verse of Tabligh (6:67) to Muhammad's precarious position in Mecca during the early years of Islam, or his interactions with the People of the Book (adherents of earlier monotheistic faiths), while Nasr et al. consider it more likely that this verse is associated with the Farewell Pilgrimage or the Ghadir Khumm. Eid al-Ghadir While 18 Dhu al-Hijjah is not a significant day on the Sunni calendar, Shia Muslims celebrate this day as the Eid al-Ghadir, the day on which Islam was completed as a religion by the appointment of Ali as Muhammad's successor. Shias honor the holiday by making pilgrimages to Karbala.
