Ash-Shama'il Al-Muhammadiyah, Book 31, Hadith 204 (In-Book)

Aisha radiyallahu anha says, The drink most liked by Rasoolullah sallallahu alaihe wasallam was that which was sweet and cold

حَدَّثَنَا ابْنُ أَبِي عُمَرَ، قَالَ‏:‏ حَدَّثَنَا سُفْيَانُ، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ‏:‏ كَانَ أَحَبَّ الشَّرَابِ إِلَى رَسُولِ اللهِ صلى الله عليه وسلم، الْحُلْوُ الْبَارِدُ‏.‏
