Making Iftaar by mistake before sunset

Question: What does the Shari’ah say regarding a person who does Iftaar by mistake before sunset?

Answer: Despite having taken all precautions, if a person happens to make Iftaar before the time by mistake with the impression that the sun has set but in reality it did not yet set, then there is neither blame nor Kaffaarah on him, but he should repeat the Roza of that day.
