A number of our companions...
A number of our companions, from Sahl Bin Ziyad, from Muhammad Bin Isa Bin Ubeyd, from Ibn Abu Umeyr, from the one who mentioned it, from: Abu Abdullah -asws said: ‘The time of the fall of the disc (sun) and the Obligation of breaking from the Fasts is that, one stands facing the Qiblah and inspects the redness which rises from the east. So when it passes overhead towards the direction of the west, so the breaking of the Fast is Obligated, and the disc falls (sun sets)’.
Ali Bin Ibrahim, from his father, and Muhammad Bin Yahya, from Ahmad Bin Muhammad, altogether from Ibn Abu Umeyr, from Hammad Bin Usman, from Al Halby, from: Abu Abdullah -asws , said, ‘He -asws was asked about the crescent, so he -asws said: ‘It is the crescent of the month. So, whenever you sight the new moon, so Fast (from next Dawn), and when you sight it (again – after a month), so break the Fasting’ .
(The crescent is never visible at the meteorological reported sunset but only after its light rays begin to disappear from the eyesight). [7] When is the Sunset (observed)? Islam is for all times, ages – so that all people can act upon its laws, and not only those who have access to meteorological data. Therefore, in Ahadith, we are informed about the sunset, the transition of night fall, the full night (when the starts become visible) leading to the breaking of the Dawn.
