Hadith #21

عَلِيُّ بْنُ اَلْحَسَنِ بْنِ فَضَّالٍ عَنْ إِبْرَاهِيمَ بْنِ أَبِي بَكْرِ بْنِ أَبِي سَمَّاكٍ عَنْ زَكَرِيَّا اَلْمُؤْمِنِ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ:» اَلَّذِي يَقْضِي شَهْرَ رَمَضَانَ هُوَ بِالْخِيَارِ فِي اَلْإِفْطَارِ مَا بَيْنَهُ وَ بَيْنَ أَنْ تَزُولَ اَلشَّمْسُ وَ فِي اَلتَّطَوُّعِ مَا بَيْنَهُ وَ بَيْنَ أَنْ تَغِيبَ اَلشَّمْسُ«.

Ali ibn al-Hasan ibn Faddal, from Ibrahim ibn Abi Bakr ibn Abi Sammak, from Zakariyya al-Mumin, from Ishaq ibn Ammar, from Abu Abdillah , peace be upon him: Imam said: “The one who is making up the month of Ramadan has the choice regarding breaking the fast between himself and when the sun declines, and in voluntary fasting, between himself and when the sun sets.”
