That the Prophet ﷺ entered upon her on Friday while she was fasting. He asked: Did you fast yesterday ? She said: No. He again asked: Do you intend to fast tomorrow ? She said: No. He said: So break your fast. (Using translation from Abū Dāʾūd 2422)
دَخَلَ عَلَيَّ رَسُولُ اللهِ ﷺ وَأَنَا صَائِمَةٌ يَوْمَ الْجُمُعَةِ فَقَالَ «أَصُمْتِ أَمْسِ؟» قُلْتُ لَا قَالَ «أَتُصُومِينَ غَدًا؟» قُلْتُ لَا قَالَ «فَأَفْطِرِي»
