Anas (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ 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 ﷺ 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)).
