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.

So pray to your Lord, the prayer of the Festival of Immolation (‘īd al-nahr), and sacrifice, your offering.

Indeed it is your antagonist, your hater, who is the severed one, refraining from all [acts of] good, or the one whose line of offspring will be severed [by his not having any]: this was revealed regarding al-‘Āsī b. Wā’il, who called the Prophet (s) al-abtar, ‘the severed one’, when his son al-Qāsim died.
