A traveler by plane should not break fast based on the time on the watch or a phone call

A: If a fasting person is on a plane and learns either by checking the time (Part No. 10; Page No. 137) on their watch or being informed by a phone call that it is time in the country over which the plane is flying to break Sawm, but they can still see the sun because of the altitude at which the plane is flying, it is not permissible for them to break Sawm because Allah (Exalted be He) says: ...then complete your Saum (fast) till the nightfall The time limit (i.e. Nightfall) specified by this Ayah is not met in the case in question, since the sun continues to be seen. However, if a fasting person breaks Sawm in a given country after the setting of the sun, but when the plane takes off they still can see the sun, they should retain their state of having broken Sawm because they fall under the same ruling as the residents of the country from which they took off, where the sun has set while they were there.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
