183يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ كُتِبَ عَلَيْكُمُ ٱلصِّيَامُ كَمَا كُتِبَ عَلَى ٱلَّذِينَ مِن قَبْلِكُمْ لَعَلَّكُمْ تَتَّقُونَ
184أَيَّامًا مَّعْدُودَٰتٍ ۚ فَمَن كَانَ مِنكُم مَّرِيضًا أَوْ عَلَىٰ سَفَرٍ فَعِدَّةٌ مِّنْ أَيَّامٍ أُخَرَ ۚ وَعَلَى ٱلَّذِينَ يُطِيقُونَهُۥ فِدْيَةٌ طَعَامُ مِسْكِينٍ ۖ فَمَن تَطَوَّعَ خَيْرًا فَهُوَ خَيْرٌ لَّهُۥ ۚ وَأَن تَصُومُوا۟ خَيْرٌ لَّكُمْ ۖ إِن كُنتُمْ تَعْلَمُونَ
[183-184] O Believers, the Fast has been made obligatory on you just as it was prescribed for the followers of the Prophets before you. It is expected that this will produce piety in you.183 The Fast is to be observed for a fixed number of days. If, however, anyone of you be sick or on a journey, he should fast the same number of other days. As for those who can fast (but do not), the expiation of this shall be the feeding of one needy person for one fast day, and whoso does more than this 184 with a willing heart does it for his own good. But if you understand the thing, it is better for you to observe the Fast.185
183Islam proceeded step by step and by degrees in the imposition of its obligatory duties. The same was done in the case of the Fast. At first the Holy Prophet (upon whom be peace) advised the Muslims to observe fasts only for three days in a month but this was not obligatory. Then in the second year of the Hijrah, this Command (v. 183) about fasting in the month of Ramadan was revealed. This, however, left an option for those who were able to fast but did not. They were required to feed one poor man as an expiation of one day's fast (v. 184). Then, later, the final commandment contained in the next verse (185) modified this, and the concession for able-bodied people was withdrawn, but retained for a sick person or wayfarer and by analogy for a pregnant or a suckling woman and for those old people who were not able to fast.
In a lengthy statement quoted by lmam Ahmad bin Hanbal, Hadrat Mu'az hilt Jabal says: "The Salat and the Fast took their present form gradually. At first the Muslims faced Jerusalem during the Salat but after some years they were commanded to turn their faces towards the Ka`abah, Makkah. Besides this, at first they used to inform one another about the time of each Salat but afterwards the same was proclaimed by means of Azan (the call for prayer). (As to the Fast), when the Holy Prophet migrated to Al-Madinah, he observed fasts for three days in a month and also on the tenth of Muharram. Then Allah made it obligatory to fast during the whole month of Ramadan but allowed the feeding of one person as an expiation for one who did not observe fasts, though he could. Afterwards this concession of feeding one person for one day of fast was cancelled in the case of healthy persons and the one not on a journey (Ibn Kathir, p.2 14).
Bukhari, Muslim, Abu Dawud and other scholars have also quoted Traditions from Hadrat `A'ishah, `Abdullah bin `Umar, and `Abdullah bin Mas'ud to the same effect. In support of the same, Ibn Jarir Tabari, a famous commentator of the Qur'an, has quoted Traditions citing the authority in full from several Companions and their followers. In one of these Traditions, he quotes the following explanation of Hadrat Mu'az bin Jabal: "As the Arabs were not used to fasting, it was hard for them at first to observe fasts. They were, therefore, given the option to feed one poor person on the day they did not observe fast during the month of Ramadan. Afterwards a Commandment was revealed, cancelling this concession except in the case of a sick person or one on a journey". He quotes another tradition from Ibn `Abbas to this effect. In the first Commandment (v.184), Allah had allowed expiation for fasts even for an able-bodied person who could fast but did not. In verse 185 which was revealed next year, the concession for an able-bodied person was cancelled but was retained for a sick person or a wayfarer.
184More than this": to feed more than one person for each fasting day, or to feed one as well as observe the fast.
185The fast commandment about fasting contained in vv. 183-84 was revealed in the second year of Hijrah before the battle of Badr. The subsequent verses were revealed a year later but were inserted here because they dealt with the same matter.
