إِنَّا أَعْطَيْنَاكَ الْكَوْثَرَ فَصَلِّ لِرَبِّكَ وَانْحَرْ
We have granted you al-Kawthar; therefore pray to your Lord and sacrifice. (Al-Kawthar 108:1–2)
The first clause uses first-person divine speech (“إِنَّا”), while the second introduces the third-person title “رَبِّكَ”. This is a shift from first-person reference to a divine attribute.
The title “Lord” makes the link between generosity, lordship and worship especially explicit.
