Riyad as-Salihin, Book 9, Hadith 1239 (In-Book) ⓘ

Anas (May Allah be pleased with him) reported: The Messenger of Allah used to break his Saum (fasting) before performing Maghrib prayer with three fresh date-fruits; if there were no fresh date- fruits, he will eat three dry dates; and if there were no dry date- fruits; he would take three draughts of water.[At- Tirmidhi].

وعن أنس رضي الله عنه قال كان رسول الله صلى الله عليه وسلم يفطر قبل أن يصلي على رطبات، فإن لم تكن رطبات فتميرات فإن لم تكن تميرات حسا حسوات من ماء‏.‏ ‏(‏‏(‏رواه أبو داود والترمذي وقال‏:‏ حديث حسن‏)‏‏)‏‏.‏
