Book Number: 007 / Hadith Number: 2350
Narated By Abdullah ibn Umar : Marwan ibn Salim al-Muqaffa' said: I saw Ibn Umar holding his bread with his hand and cutting what exceeded the handful of it. He (Ibn Umar) told that the Prophet (pbuh) said when he broke his fast: Thirst has gone, the arteries are moist, and the reward is sure, if Allah wills.
