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..
