2ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ فَضَّالٍ عَنِ ابْنِ بُكَيْرٍ عَنْ عُبَيْدِ بْنِ زُرَارَةَ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ إِذَا خَرَجَ الرَّجُلُ فِي شَهْرِ رَمَضَانَ بَعْدَ الزَّوَالِ أَتَمَّ الصِّيَامَ فَإِذَا خَرَجَ قَبْلَ الزَّوَالِ أَفْطَرَ.

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from ibn Bukayr from ‘Ubayd ibn Zurarah who has said the following: “Abu ‘Abd Allah , has said, ‘If one comes out for a journey in the month of Ramadan after Zawal (declining of the sun toward the west at noontime) one is required to complete his fast. If one comes out before Zawal (declining of the sun toward the west at noontime), then one must stop fasting.’”
