It is narrated from Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said to me: "O Ali! When you are fasting in the month of Ramadan, recite this supplication after breaking your fast: 'Allahumma laka sumtu, wa 'alayka tawakkaltu, wa 'ala rizqika aftartu' (O Allah, for You alone I fasted, in You alone I trusted, and with the provision You granted I broke my fast). Then a reward equal to that of all the people who fasted that day will be written for you, without the reward of those fasting people themselves being reduced in the least."
