All perfect praise be to Allah, The Lord of The Worlds; and may his blessings and peace be upon our Prophet Mohammad and upon all his family and companions.
On the Day of Annahr (10th of Dhul Hijjah/ Day of Eid), a pilgrim is allowed to perform four actions: Stoning the pebbles at Jamrat al-A`qaba Al-Kobra, slaughtering for the one offering Tamattu` and Qiraan Hajj, cutting hair or trimming it and Tawaf Al-Ifadah (circumambulation around the Ka`bah).
The Sunnah is that the pilgrim should perform these actions according to the above mentioned order. The majority of the Muslim scholars-including the Shafites- are of the view that this order is a Sunnah not an obligation (Waajib), and if the pilgrim advanced one and delayed another, he is free from the liability; however, it is disliked for him to violate the Sunnah. If he did violate the Sunnah intentionally or forgetfully, whether he was familiar with the order or not, he doesn`t have to slaughter a sheep.
Al-Imam An-Nawawi (May Allah bless him) said: "A pilgrim is permitted to perform four actions on the Day of Annahr after he arrives at Mina: Stoning the pebbles at Jamrat al A`qaba, slaughtering, cutting hair and Tawaf Al-Ifadah. This is their order in Sunnah." {Al-Majmou`, vol.8/pp.207}. And Allah Knows Best.
