قَالَ مَالِك : وَإِذَا أَرَادَ أَنْ يَخْرُجَ فِي رَمَضَانَ فَطَلَعَ لَهُ الْفَجْرُ وَهُوَ بِأَرْضِهِ قَبْلَ أَنْ يَخْرُجَ فَإِنَّهُ يَصُومُ ذَلِكَ الْيَوْمَ
Imam Malik, may Allah have mercy on him, said: And when one intends to travel in Ramadan and morning comes upon him while he is still in the city, then he should fast that day.
