TIRMIDHI 798:
from Salamah b. al-Akwaʿ —
"When the following was revealed: 'And for those upon whom it is difficult, (they may) feed a poor person' - if one of us wanted we would not fast, and pay the ransom, until the Ayah after it was revealed abrogating it."
الترمذي ٧٩٨:
عن سلمه بن الاكوع —
لَمَّا نَزَلَتْ (وَعَلَى الَّذِينَ يُطِيقُونَهُ فِدْيَةٌ طَعَامُ مِسْكِينٍ ) كَانَ مَنْ أَرَادَ مِنَّا أَنْ يُفْطِرَ وَيَفْتَدِيَ حَتَّى نَزَلَتِ الآيَةُ الَّتِي بَعْدَهَا فَنَسَخَتْهَا
