[Machine] The Prophet (PBUH) used to like pebbles and would hold them in his hand. One day, he entered the mosque holding one in his hand and he saw some sputum in the direction of the mosque's qibla. He wiped it away with the pebble he was holding and then turned towards the people angry and said, "Does anyone of you like to have a person face him and spit in his face? When one of you stands up to pray, he is actually facing his Lord and the Angel is on his right. So, he should not spit in front of him or to his right side. Instead, he should spit to his left side below his left foot. But if there is an urgency, then he can do so rapidly and say, 'In this way.' And he should then perform the ritual purification and wipe some portion of his garment to remove the remaining traces."
كَانَ رَسُولُ اللَّهِ ﷺ تُعْجِبُهُ الْعَرَاجِينُ يُمْسِكُهَا بِيَدِهِ فَدَخَلَ يَوْمًا الْمَسْجِدَ وَفِي يَدِهِ مِنْهَا وَاحِدَةٌ فَرَأَى نُخَامَةً فِي قِبْلَةِ الْمَسْجِدِ فَحَتَّهَا بِهِ حَتَّى أَنْقَاهَا ثُمَّ أَقْبَلَ عَلَى النَّاسِ مُغْضَبًا فَقَالَ «أَيُحِبُّ أَحَدُكُمْ أَنْ يَسْتَقْبِلَهُ الرَّجُلُ فَيَبْصُقَ فِي وَجْهِهِ إِنَّ أَحَدَكُمْ إِذَا قَامَ إِلَى الصَّلَاةِ فَإِنَّمَا يَسْتَقْبِلُ بِهِ رَبَّهُ وَالْمَلَكُ عَنْ يَمِينِهِ فَلَا يَبْصُقْ بَيْنَ يَدَيْهِ وَلَا عَنْ يَمِينِهِ وَلَكِنْ عَنْ يَسَارِهِ تَحْتَ قَدَمِهِ الْيُسْرَى فَإِنْ عَجِلَتْ بِهِ بَادِرَةٌ فَلْيَقُلْ هَكَذَا» وَتَفَلَ فِي ثَوْبِهِ وَرَدَّ بَعْضَهُ بِبَعْضٍ
