[Machine] The Prophet ﷺ passed by a boy named Rabah who was praying. He blew into his prostration and said to him, "O Rabah, do not blow. Whoever blows, he has spoken."  

مَرَّ النَّبِيُّ ﷺ بِغُلَامٍ لَهُمْ يُقَالُ لَهُ رَبَاحٌ وَهُوَ يُصَلِّي فَنَفَخَ فِي سُجُودِهِ فَقَالَ لَهُ «يَا رَبَاحُ لَا تَنْفُخْ إِنَّ مَنْ نَفَخَ فَقَدْ تَكَلَّمَ»
