Seeing the Moon During the Day

Q: Hil-4: I have read in a book that when the new moon is sighted during the day, Iftaar should be made (the fast terminated), even if there remains still two hours for sunset. Is this true?

Answer: The stated ruling is incorrect. It is not permissible to break the fast before sunset even if the moon is sighted.
