Water of Al-Kawthar
Scholars have said that if a person dreams of drinking from the water of Al-Kawthar, they may attain leadership and honor, and triumph over their enemies. This interpretation is supported by the Quranic verse: "Indeed, We have granted you, [O Muhammad], Al-Kawthar."
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
