حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا بَكْرُ بْنُ مُضَرَ، عَنْ عَمْرِو بْنِ الْحَارِثِ، عَنْ بُكَيْرِ بْنِ عَبْدِ اللَّهِ، عَنْ يَزِيدَ، مَوْلَى سَلَمَةَ بْنِ الأَكْوَعِ عَنْ سَلَمَةَ، قَالَ لَمَّا نَزَلَتْ ‏ End hadith 4‏ كَانَ مَنْ أَرَادَ أَنْ يُفْطِرَ وَيَفْتَدِيَ حَتَّى نَزَلَتِ الآيَةُ الَّتِي بَعْدَهَا فَنَسَخَتْهَا‏.‏ مَاتَ بُكَيْرٌ قَبْلَ يَزِيدَ‏.‏

Narrated Salama: When the Divine Revelation: "For those who can fast, they had a choice either fast, or feed a poor for every day," (2.184) was revealed, it was permissible for one to give a ransom and give up fasting, till the Verse succeeding it was revealed and abrogated it.
