"Did the Messenger of Allah ﷺ eat Naqi – meaning refined (flour)?” So Sahl said: “The Messenger of Allah ﷺ did not see Naqi until he met Allah.” It was said to him: “Did you have sifters during the time of the Messenger of Allah ﷺ?” He said: “There were no sifters for us.” They said: “How did you prepare the barley?”He said: “We would blow it so (the husk) would fly off of it, then we would add water so we could knead it.” (Hasan)  

أَنَّهُ قِيلَ لَهُ أَكَلَ رَسُولُ اللَّهِ ﷺ النَّقِيَّ يَعْنِي الْحُوَّارَى فَقَالَ سَهْلٌ مَا رَأَى رَسُولُ اللَّهِ ﷺ النَّقِيَّ حَتَّى لَقِيَ اللَّهَ فَقِيلَ لَهُ هَلْ كَانَتْ لَكُمْ مَنَاخِلُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ قَالَ مَا كَانَتْ لَنَا مَنَاخِلُ قِيلَ فَكَيْفَ كُنْتُمْ تَصْنَعُونَ بِالشَّعِيرِ قَالَ كُنَّا نَنْفُخُهُ فَيَطِيرُ مِنْهُ مَا طَارَ ثُمَّ نُثَرِّيهِ فَنَعْجِنُهُ  

My father told me: I asked Sahl bin Sa’d: “Did you ever see dough made from well-sifted flour?” He said: “I never saw dough made from well-sifted flour until the Messenger of Allah ﷺ passed away.” I said: “Did they have sieves at the time of the Messenger of Allah ﷺ?” He said: “I never saw a sieve until the Messenger of Allah ﷺ passed away.” I said: “How did you eat barley that was not sifted?” He said: “We used to blow on it, and whatever flew away, flew away, and whatever was left we made dough with it.” (Using translation from Ibn Mājah 3335)   

«مَا رَأَيْتُ النِّقْيَ حَتَّى قَبَضَ اللهُ رَسُولَ اللهِ ﷺ» قُلْتُ هَلْ كَانَتْ لَكُمْ مَنَاخِلُ فِي عَهْدِ رَسُولِ اللهِ ﷺ؟ قَالَ «مَا رَأَيْتُ مُنْخُلًا حَتَّى قَبَضَ اللهُ رَسُولَهُ» قُلْتُ كَيْفَ تَأْكُلُونَ الشَّعِيرَ غَيْرَ مَنْخُولٍ؟ قَالَ «نَعَمْ نَنْفُخُهُ ثُمَّ يَطِيرُ مِنْهُ مَا طَارَ»
