Al Baqarah Ayah 184

أَيَّامًا مَّعْدُودَٲتٍ‌ۚ فَمَن كَانَ مِنكُم مَّرِيضًا أَوْ عَلَىٰ سَفَرٍ فَعِدَّةٌ مِّنْ أَيَّامٍ أُخَرَ‌ۚ وَعَلَى ٱلَّذِينَ يُطِيقُونَهُۥ فِدْيَةٌ طَعَامُ مِسْكِينٍ‌ۖ فَمَن تَطَوَّعَ خَيْرًا فَهُوَ خَيْرٌ لَّهُۥ‌ۚ وَأَن تَصُومُواْ خَيْرٌ لَّكُمْ‌ۖ إِن كُنتُمْ تَعْلَمُونَ ١٨٤ ?Fast a? prescribed number of days. But whoever of you is ill or on a journey, then ?let them fast? an equal number of days ?after Rama?ân?. For those who can only fast with extreme difficulty, compensation can be made by feeding a needy person ?for every day not fasted?. But whoever volunteers to give more, it is better for them. And to fast is better for you, if only you knew.
