(The Statement of Allah تعالى): “And as for those who can fast with difficulty (e.g. the aged etc.) they have (a choice either to fast or) to feed a Miskin (poor person) (for every day).” (V.2:184)
Ibn ‘Umar and Salama bin Al-Akwa‘ said that the provision of the above Verse was abrogated by the following Verse:
“The month of Ramadan in which was revealed the Qur’an... (up to)... for having guided you, so that you may be grateful to Him.” (V.2:185).
Narrated Ibn Abi Laila: The companions of Prophet Muhammad ﷺ said that when observing Saum (fast) in Ramadan was prescribed (for the first time), they could not endure it. So, whoever fed a poor person every day (of Ramadan) did not observe Saum (fast) [although he had the power to observe Saum (fast)], and was permitted to do so. Then this order was cancelled by the Verse: “...And that you observe Saum (fast) is better for you.” (V.2:184), so they were ordered to observe Saum (fast).
حَدَّثَنَا عَيَّاشٌ، حَدَّثَنَا عَبْدُ الأَعْلَى، حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَرَأَ فِدْيَةٌ طَعَامُ مَسَاكِينَ. قَالَ هِيَ مَنْسُوخَةٌ.
