Sunan Ibn Majah, Volume 4, Book 29, Hadith 3341 (DarusSalam) ⓘ

It was narrated that Ibn ‘Umar said: “One day, the Messenger of Allah said: ‘I wish that we had some white bread made of brown wheat, softened with ghee, that we could eat.’ A man from among the Ansar heard that, so he took some (of that food) and brought it to him. The Messenger of Allah said: ‘Where was this ghee kept?’ He said: ‘In a container made of mastigure skin.’ And he refused to eat it.”

حَدَّثَنَا هَدِيَّةُ بْنُ عَبْدِ الْوَهَّابِ، حَدَّثَنَا الْفَضْلُ بْنُ مُوسَى السِّيْنَانِيُّ، حَدَّثَنَا الْحُسَيْنُ بْنُ وَاقِدٍ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ذَاتَ يَوْمٍ ‏"‏ وَدِدْتُ لَوْ أَنَّ عِنْدَنَا خُبْزَةً بَيْضَاءَ مِنْ بُرَّةٍ سَمْرَاءَ مُلَبَّقَةٍ بِسَمْنٍ نَأْكُلُهَا ‏"‏ ‏.‏ قَالَ فَسَمِعَ بِذَلِكَ رَجُلٌ مِنَ الأَنْصَارِ فَاتَّخَذَهُ فَجَاءَ بِهِ إِلَيْهِ فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ فِي أَىِّ شَىْءٍ كَانَ هَذَا السَّمْنُ ‏"‏ ‏.‏ قَالَ فِي عُكَّةِ ضَبٍّ ‏.‏ قَالَ فَأَبَى أَنْ يَأْكُلَهُ ‏.‏
