Surah Al-Kawthar — Ayah 2 (108:2)
فَصَلِّ لِرَبِّكَ وَٱنۡحَرۡ ٢
English translation (Saheeh International)
So pray to your Lord and offer sacrifice [to Him alone].
Brief commentary
So be grateful to Allah for this blessing, by performing prayer for Him alone and offering sacrifice for Him, as opposed to the offerings of sacrifice the idolaters do for their idols.
