It was narrated from Ibn ‘Abbas that the Prophet ﷺ visited a man (who was sick) and said to him:
“What do you desire?” He said: “I want wheat bread.” The Prophet ﷺ said: “Whoever has wheat bread, let him send it to his brother.” Then the Prophet ﷺ said: “When a sick person among you desires something, give it to him.”

حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ الْخَلاَّلُ، حَدَّثَنَا صَفْوَانُ بْنُ هُبَيْرَةَ، حَدَّثَنَا أَبُو مَكِينٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ النَّبِيَّ ـ ﷺ ـ عَادَ رَجُلاً فَقَالَ لَهُ " مَا تَشْتَهِي " . فَقَالَ أَشْتَهِي خُبْزَ بُرٍّ . فَقَالَ النَّبِيُّ ـ ﷺ ـ " مَنْ كَانَ عِنْدَهُ خُبْزُ بُرٍّ فَلْيَبْعَثْ إِلَى أَخِيهِ " . ثُمَّ قَالَ النَّبِيُّ ـ ﷺ ـ " إِذَا اشْتَهَى مَرِيضُ أَحَدِكُمْ شَيْئًا فَلْيُطْعِمْهُ " .
