Hadith.1980 - Imam عليه السلام said:
"A man should not break his fast in the Month of Ramadan except for a rightful cause."
The compiler of this book—may Allah سبحانه وتعالى have mercy on him—commented:
"I have discussed the shortening of prayers for travelers in the chapters on prayer within this book, including the distance at which shortening becomes obligatory and those for whom offering full prayers remains mandatory."
