I heard the Prophet ﷺ delivering a sermon in which he said, "The first thing we begin with on this day of ours is the prayer. Then we return and offer the sacrifice. Whoever does this has followed our practice."
سمعت النبي ﷺ يخطب فقال: إن أول ما نبدأ من يومنا هذا أن نصلي ثم نرجع فننحر، فمن فعل فقد أصاب سنتنا.
Bukhari narrated it in "The Two Eids" (951) from Hajjaj, who said, Shuba narrated to us, who said, Zubayd informed me, who said, I heard Shaybi, from Bara, and he mentioned it. It will come at greater length in the book on udhiya.As for the congratulatory greetings for Eid, that is, people saying to one another, "May Allah accept from us and from you," one instance of this is what Muhammad bin Ziyad narrated, saying, I was with Abu Umama Bahili and others among the companions of the Messenger of Allah ﷺ, and when they returned they would say to one another, "May Allah accept from us and from you." Imam Ahmad said its chain is good (jayyid). Ibn Turkmani mentioned it in Jawhar Naqi (3/320).Another instance is what Jubayr bin Nufayr narrated, saying, when the companions of the Messenger of Allah ﷺ met on the day of Eid, they would say to one another, "May Allah accept from us and from you." Ibn Hajar said in Fath al-Bari (2/446), "We related it in Mahamiliyyat with a hasan chain."Bayhaqi narrated (3/319) through the route of Adham, the freedman of Umar bin Abdul-Aziz, who said, we used to say to Umar bin Abdul-Aziz on the two Eids, "May Allah accept from us and from you, O Commander of the Faithful," and he would return the greeting to us and would not object to it from us...As for what is reported from Wathila bin Asqa as a raised report (marfu), it is not sound. Ibn Adi narrated it in Al-Kamil (6/2276) from Muhammad bin Dahhak bin Amr bin Abu Asim, who said, Abdul-Aziz bin Muawiya narrated to us, Muhammad bin Ibrahim Shami narrated to us, Baqiya narrated to us, from Thawr, from Khalid bin Madan, from Wathila bin Asqa, who said, I met the Prophet ﷺ on the day of Eid and said, "O Messenger of Allah, may Allah accept from us and from you." He said, "Yes, may Allah accept from us and from you."Ibn Adi said, "This is a munkar report. I know of no one who narrated it from Baqiya other than this Muhammad bin Ibrahim, and most of his hadiths are not reliably preserved." End of quote.I say, this Muhammad bin Ibrahim is Ibn Ala Dimashqi Shami. Daraqutni said of him, "A liar." Ibn Hibban said, "He fabricates hadith, and it is not permissible to narrate from him except for the purpose of comparison." Abu Naeem said, "He narrated fabricated reports."Bayhaqi narrated it (3/319) through the route of Ibn Adi, and said, "I have seen it with another chain from Baqiya as a stopped report (mawquf), not raised, and I do not consider it reliably preserved."I say, this is what Tabarani narrated in Mujam al-Kabir (22/52–53) through the route of Abu Hammam Walid bin Shuja, who said, Baqiya bin Walid narrated to us, Habib bin Amr Ansari narrated to me, my father informed me, saying, I met Wathila on the day of Eid and said, "May Allah accept from us and from you." He said, "Yes, may Allah accept from us and from you."Dhahabi related in Al-Mizan, Al-Mughni, and Diwan Al-Duafa from Daraqutni that he said, "Habib bin Amr is unknown (majhul)."Likewise, what is reported concerning the disapproval of this greeting is not sound. It is what Naeem bin Hammad narrated, saying, Abdul-Khaliq bin Zayd bin Waqid Dimashqi narrated to us, from his father, from Makhul, from Ubada bin Samit, who said, I asked the Messenger of Allah ﷺ about people's saying on the two Eids, "May Allah accept from us and from you," and he said, "That is a practice of the People of the two Scriptures," and he disapproved of it.Bayhaqi narrated it and said, "Abdul-Khaliq bin Zayd is one whose hadith is munkar," as Bukhari stated. Ibn Hajar said, "Its chain is daif."
