It is Sunnah to enjoy pleasant, cool drink. ʿĀʾishah said: “The most beloved drink to the Messenger of Allah ﷺ was the sweet, cool one.” (Tirmidhī — ṣaḥīḥ). Enjoying Allah's lawful, wholesome blessings — with gratitude — is part of the Sunnah.
العربية: عن عائشة رضي الله عنها قالت: «كان أحبّ الشراب إلى رسول الله ﷺ الحلوَ الباردَ». (الترمذي).
Enjoy a cool, pleasant lawful drink — and thank Allah for it, as the Prophet ﷺ loved it.
