Breaking the fast when the sun sets

Q 2: Allah (Exalted be He) says: ...then complete your Saum (fast) till the nightfall It is established that Shiites quote this verse as evidence that breaking the fast should not take place except after seeing the stars in the sky, which for them is the actual night, as stated in the story of Prophet Ibrahim (Abraham) (peace be upon him) in which Allah says: When the night covered him over with darkness he saw a star. Then, what is the reply to their claim, keeping in mind that they deny some Hadiths which we quoted for them as evidence for breaking the fast upon the setting of the sun. They also claim that the Holy Qur'an has more authority than the Hadith?

A: If the sun has set, then it is the time to break the fast. The setting of the sun is the inception of the night, according to the Prophet's (peace be upon him) statement: When night falls from this side and the day disappears from this side (Part No. 9; Page No. 29) and the sun has set, then one should break his fast. .May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
