[Machine] The Prophet ﷺ used to wipe the faces of his companions before he would say the takbeer (Allahu Akbar) for prayer. Once, he wiped their faces and accidentally touched something from a creature, so he wiped his own face and left me. So I went back and washed myself, then I came back for another prayer and he wiped my face and said, "Return to your religion which is the best. The heavens have cleared."  

كَانَ النَّبِيُّ ﷺ إِذَا قَامَ إِلَى الصَّلَاةِ مَسَحَ وُجُوهَ أَصْحَابِهِ قَبْلَ أَنْ يُكَبِّرَ فَأَصَبْتُ شَيْئًا مِنْ خَلُوقٍ فَمَسَحَ النَّبِيُّ ﷺ وُجُوهَ أَصْحَابِهِ وَتَرَكَنِي قَالَ فَرَجَعْتُ وَغَسَلْتُهُ ثُمَّ جِئْتُ إِلَى الصَّلَاةِ الْأُخْرَى فَمَسَحَ وَجْهِي وَقَالَ عَادَ لِخَيْرِ دِينِهِ الْعَلَاء تَابَ وَاسْتَهَلَّتِ السَّمَاءُ
