quran:108:1 – In the name of Allah, the Entirely Merciful, the Especially Merciful.

Indeed, We have granted you, ˹O Muhammad˺, al-Kawthar.  

We have assuredly given you, O Muhammad (s), Abundance — ˹the name of˺ a river in Paradise and his ˹the Prophet’s˺ pool around which his community shall gather; al-kawthar also means the abundant good ˹that has been given to the Prophet˺, such as prophethood, the Qur’ān, intercession, and the like.
القرآن:١٠٨:١ – بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ

إِنَّا أَعْطَيْنَاكَ الْكَوْثَرَ  

{إنا أعطيناك} يا محمد {الكوثر} هو نهر في الجنة هو حوضه ترد عليه أمته، والكوثر: الخير الكثير من النبوَّة والقرآن والشفاعة ونحوها.
