أَيّامًا مَعدوداتٍ ۚ فَمَن كانَ مِنكُم مَريضًا أَو عَلىٰ سَفَرٍ فَعِدَّةٌ مِن أَيّامٍ أُخَرَ ۚ وَعَلَى الَّذينَ يُطيقونَهُ فِديَةٌ طَعامُ مِسكينٍ ۖ فَمَن تَطَوَّعَ خَيرًا فَهُوَ خَيرٌ لَهُ ۚ وَأَن تَصوموا خَيرٌ لَكُم ۖ إِن كُنتُم تَعلَمونَ

For a set number of days. However, if any of you is ill or on a journey, then on other days. And upon those who are able—a ransom of feeding a poor person. If you voluntarily do good, it’s better for you. And if you fast, it is better for you, if only you knew.
