It was narrated that Anas bin Malik said:
“The Prophet ﷺ entered upon a sick person to visit him. He said: ‘Do you long for anything? Do you long for Ka’k (a type of bread)?’ He said: ‘Yes.’ So they sent someone to bring some Ka’k 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 فَقَالَ " أَتَشْتَهِي شَيْئًا أَتَشْتَهِي كَعْكًا " . قَالَ نَعَمْ . فَطَلَبُوا لَهُ .
