عَن أبي أَيُّوب قَالَ: كُنَّا عِنْدَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقُرِّبَ طَعَامٌ فَلَمْ أَرَ طَعَامًا كَانَ أَعْظَمَ بَرَكَةً مِنْهُ أَوَّلَ مَا أَكَلْنَا وَلَا أَقَلَّ بَرَكَةً فِي آخِرِهِ قُلْنَا: يَا رَسُولَ اللَّهِ كَيْفَ هَذَا؟ قَالَ: «إِنَّا ذَكَرْنَا اسْمَ اللَّهِ عَلَيْهِ حِينَ أَكَلْنَا ثُمَّ قَعَدَ مَنْ أَكَلَ وَلَمْ يُسَمِّ اللَّهَ فَأَكَلَ مَعَهُ الشَّيْطَانُ» . رَوَاهُ فِي شرح السّنة
Translation

Ibn ‘Umar reported God's messenger as saying, “I wish I had a white loaf made from tawny wheat and softened with clarified butter and milk.” A man who was present rose up and getting one brought it. He asked what it had been in, and when he was told it had been in a lizard skin, he told him to take it away. Abu Dawud and Ibn Majah transmitted it, Abu Dawud saying this is a tradition which is rejected.
