إِنَّا أَعْطَيْنَاكَ الْكَوْثَرَ
فَصَلِّ لِرَبِّكَ وَانْحَرْ
إِنَّ شَانِئَكَ هُوَ الْأَبْتَرُ
Allah said to his Prophet Muhammad صلى الله عليه وسلم "Verily,
We have granted you Al-Kawthar, Therefore turn in prayer to your Lord and sacrifice, For he who hates you, he will be cut off"
In this Allah promised His Messenger with good and that his enemies would be cut off and left deficient, and so turned him صلى الله عليه وسلم towards gratitude for such favours.
The promise was revealed to Muhammad صلى الله عليه وسلم at a time when his followers were few and his enemies were many. It exemplifies how Allah looked after His Messenger صلى الله عليه وسلم, who was facing great hardships in his da'awah to the stubborn Meccan people, pulling him ever closer with comforting words. This is in contrast to the condemnation for his despicable enemies (shaaniaka).
The truthfulness of this promise is shown in the reality of goodness, guidance and Iman, which is in contrast to evil, misguidance and kufr.
