Arabic hadith text
وَعَن أنس قَالَ: مَا أَعْلَمُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَأَى رَغِيفًا مُرَقَّقًا حَتَّى لَحِقَ بِاللَّهِ وَلَا رَأَى شَاةً سَمِيطًا بِعَيْنِهِ قَطُّ. رَوَاهُ البُخَارِيّ
Translation
Anas said he was not aware of the Prophet having seen a thin loaf till he met God, [i.e. during his lifetime.] nor did he ever see with his eye a sheep roasted in its skin. Bukhari transmitted it.
