Sahih al-Bukhari 7399
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا هِشَامٌ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، قَالَ ضَحَّى النَّبِيُّ صلى الله عليه وسلم بِكَبْشَيْنِ، يُسَمِّي وَيُكَبِّرُ‏.‏
Anas:

The Prophet (ﷺ) slaughtered two rams as sacrifice and mentioned Allah's Name and said, "Allahu-Akbar" while slaughtering).
