Prophet (ﷺ) used to say at the time of slaughter -

بِسْمِ اللَّهِ اَللَّهُمَّ تَقَبَّلْ مِنْ مُحَمَّدٍ وَآلِ مُحَمَّدٍ وَمِنْ أُمَّةِ مُحَمَّدٍ

Bismillaahi, Allah-humma Taqabbal min Muhammadin wa Al-i-Muhammadin, wa min Ummati Muhammadin

In the name of Allah, O Allah, accept it from Muhammad, Muhammad's family and from Muhammad's Ummah (followers) Then he sacrificed it.
