It was narrated that Anas bin Malik said:
“The Prophet ﷺ went to visit a sick person, and said: ‘Do you want anything? Do you want cake?’ He said: ‘Yes.’ So they looked for some for him.”

حَدَّثَنَا سُفْيَانُ بْنُ وَكِيعٍ، حَدَّثَنَا أَبُو يَحْيَى الْحِمَّانِيُّ، عَنِ الأَعْمَشِ، عَنْ يَزِيدَ الرَّقَاشِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ دَخَلَ النَّبِيُّ ﷺ عَلَى مَرِيضٍ يَعُودُهُ قَالَ " أَتَشْتَهِي شَيْئًا أَتَشْتَهِي كَعْكًا " . قَالَ نَعَمْ . فَطَلَبُوا لَهُ .
