"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) (Using translation from Tirmidhī 2364)   

أَنَّهُ قِيلَ لَهُ هَلْ رَأَى رَسُولُ اللهِ ﷺ النَّقِيَّ قَبْلَ مَوْتِهِ بِعَيْنِهِ يَعْنِي الْحُوَّارَى؟ قَالَ مَا رَأَى رَسُولُ اللهِ ﷺ النَّقِيَّ بِعَيْنِهِ حَتَّى لَقِيَ اللهَ ﷻ فَقِيلَ لَهُ هَلْ كَانَ لَكُمْ مَنَاخِلُ عَلَى عَهْدِ رَسُولِ اللهِ ﷺ؟ قَالَ مَا كَانَتْ لَنَا مَنَاخِلُ قِيلَ لَهُ فَكَيْفَ كُنْتُمْ تَصْنَعُونَ بِالشَّعِيرِ؟ قَالَ نَنْفُخُهُ فَيَطِيرُ مِنْهُ مَا طَارَ  

[Machine] I asked Sahl bin Sa'd, "Were there date palm groves during the time of the Prophet Muhammad, ﷺ ?" He said, "I did not see any palm groves during that time, and the Messenger of Allah, ﷺ , never ate ground barley until he passed away." I asked, "What did you do then?" He said, "We used to grind it, then blow on it so that whatever flew away would stay away, and whatever clung to it would stick."  

قُلْتُ لِسَهْلِ بْنِ سَعْدٍ هَلْ كَانَتِ الْمَنَاخِلُ عَلَى عَهْدِ رَسُولِ اللهِ ﷺ؟ قَالَ «مَا رَأَيْتُ مُنْخُلًا فِي ذَلِكَ الزَّمَانِ وَمَا أَكَلَ رَسُولُ اللهِ ﷺ شَعِيرًا مَنْخُولًا حَتَّى فَارَقَ الدُّنْيَا» قُلْتُ كَيْفَ كُنْتُمْ تَصْنَعُونَ؟ قَالَ «كُنَّا نَطْحَنُهُ ثُمَّ نَنْفُخُهُ فَيَطِيرُ مَا طَارَ ويَسْتَمْسِكُ مَا يَسْتَمْسِكُ»
