Ibn ‘Abbas said the Prophet (ﷺ) once visited a man and asked him what he would like. When he replied that he would like some wheaten bread the Prophet (ﷺ) said, “Let anyone who has any wheaten bread send it to his brother,” adding, “When any of you has an invalid who expresses a desire for something, give it to him to eat.” Ibn Majah transmitted it.

وَعَنِ ابْنِ عَبَّاسٍ: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَادَ رَجُلًا فَقَالَ لَهُ: «مَا تستهي؟» قَالَ: أشتهي خبز بر. قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ كَانَ عِنْدَهُ خُبْزُ بُرٍّ فَلْيَبْعَثْ إِلَى أَخِيهِ» . ثُمَّ قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا اشْتَهَى مَرِيضُ أحدكُم شَيْئا فليطعمه» . رَوَاهُ ابْن مَاجَه
