Messenger of Allah ﷺ saw sputum on the wall of the mosque in the direction of the Qibla and scraped it off. He faced the people and said, "Whenever any one of you is praying, he should not spit in front of him because in the prayer Allah is in front of him."  

أَنَّ رَسُولَ اللَّهِ ﷺ رَأَى بُصَاقًا فِي جِدَارِ الْقِبْلَةِ فَحَكَّهُ ثُمَّ أَقْبَلَ عَلَى النَّاسِ فَقَالَ إِذَا كَانَ أَحَدُكُمْ يُصَلِّي فَلاَ يَبْصُقْ قِبَلَ وَجْهِهِ فَإِنَّ اللَّهَ قِبَلَ وَجْهِهِ إِذَا صَلَّى  

The Messenger of Allah ﷺ saw spittle on the wall towards Qibla, and scratched it away and then turning to the people said: When any one of you prays, he must not spit in front of him, for Allah is in front of him when he is engaged in prayer.  

أَنَّ رَسُولَ اللَّهِ ﷺ رَأَى بُصَاقًا فِي جِدَارِ الْقِبْلَةِ فَحَكَّهُ ثُمَّ أَقْبَلَ عَلَى النَّاسِ فَقَالَ إِذَا كَانَ أَحَدُكُمْ يُصَلِّي فَلاَ يَبْصُقْ قِبَلَ وَجْهِهِ فَإِنَّ اللَّهَ قِبَلَ وَجْهِهِ إِذَا صَلَّى  

"When any one of you is praying, let him not spit in front of him, for Allah is in front of him when he prays."  

أَنَّ رَسُولَ اللَّهِ ﷺ رَأَى بُصَاقًا فِي جِدَارِ الْقِبْلَةِ فَحَكَّهُ ثُمَّ أَقْبَلَ عَلَى النَّاسِ فَقَالَ إِذَا كَانَ أَحَدُكُمْ يُصَلِّي فَلاَ يَبْصُقَنَّ قِبَلَ وَجْهِهِ فَإِنَّ اللَّهَ ﷻ قِبَلَ وَجْهِهِ إِذَا صَلَّى  

Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah ﷺ saw spittle on the wall of the qibla and scraped it off. Then he went up to the people and said, "Do not spit in front of you when you are praying, because Allah, the Blessed and Exalted, is in front of you when you pray."  

أَنَّ رَسُولَ اللَّهِ ﷺ رَأَى بُصَاقًا فِي جِدَارِ الْقِبْلَةِ فَحَكَّهُ ثُمَّ أَقْبَلَ عَلَى النَّاسِ فَقَالَ إِذَا كَانَ أَحَدُكُمْ يُصَلِّي فَلاَ يَبْصُقْ قِبَلَ وَجْهِهِ فَإِنَّ اللَّهَ تَبَارَكَ وَتَعَالَى قِبَلَ وَجْهِهِ إِذَا صَلَّى  

"When any one of you is praying, let him not spit in front of him, for Allah is in front of him when he prays." (Using translation from Nasāʾī 724)  

إِنَّ رَسُولَ اللهِ ﷺ رَأَى بُصَاقًا فِي جِدَارِ الْقِبْلَةِ فَحَكَّهُ ثُمَّ أَقْبَلَ عَلَى النَّاسِ فَقَالَ إِذَا كَانَ أَحَدُكُمْ يُصَلِّي فَلَا يَبْصُقَنَّ قِبَلَ وَجْهِهِ فَإِنَّ اللهَ ﷻ قِبَلَ وَجْهِهِ إِذَا صَلَّى قَالَ إِسْحَاقُ فِي حَدِيثِهِ بُصَاقًا  

[Machine] The Messenger of Allah ﷺ saw some impurity in the direction of the mosque, so he cleaned it up and then faced the people and said, "If any of you is in prayer, he should not spit towards the direction of his face, for indeed Allah, the Most High, faces the face of one of you when he is in prayer."  

أَنَّ رَسُولَ اللهِ ﷺ رَأَى نُخَامَةً فِي قِبْلَةِ الْمَسْجِدِ فَحَتَّهَا ثُمَّ أَقْبَلَ عَلَى النَّاسِ فَقَالَ إِذَا كَانَ أَحَدُكُمْ فِي الصَّلَاةِ فَلَا يَتَنَخَّمْ قِبَلَ وَجْهِهِ فَإِنَّ اللهَ تَعَالَى قِبَلَ وَجْهِ أَحَدِكُمْ إِذَا كَانَ فِي الصَّلَاةِ  

"إِذا كانَ أحدُكُمْ يُصَلِّي فلا يَبْصُقْ قِبَلَ وجْهه، فإِنَّ الله قِبلَ وجهه إِذا صَلَّى" .
