مَنْ أَفْطَرَ يَوْمًا مِنْ رَمَضَانَ مِنْ غَيْرِ رُخْصَةٍ وَلَا مَرَضٍ، لَمْ يَقْضِ عَنْهُ صَوْمُ الدَّهْرِ كُلِّهِ وَإِنْ صَامَهُ
Translation: Whoever breaks a day of Ramadan fasting without concession or illness cannot recover the special merit of that day merely by fasting for an entire lifetime.

أَفْطَرَ means “broke or abandoned the fast.” مِنْ غَيْرِ رُخْصَةٍ وَلَا مَرَضٍ means “without a lawful concession or illness.” لَمْ يَقْضِ عَنْهُ conveys that the lost special merit cannot simply be replaced. In وَإِنْ صَامَهُ, إِنْ is conditional: “even if he fasted it.”
The lesson emphasizes the gravity of deliberately missing a Ramadan fast without valid cause. Important distinction: The warning concerns the unique merit of Ramadan; it does not mean that the legal duty of making up a missed fast vanishes or that making it up has no value.
