وَعَن السَّائِب بن خَلاد - وَهُوَ رَجُلٍ مِنْ أَصْحَابِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنْ رَجُلًا أَمَّ قَوْمًا فَبَصَقَ فِي الْقِبْلَةِ وَرَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَنْظُرُ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حِينَ فَرَغَ: «لَا يُصَلِّي لَكُمْ» . فَأَرَادَ بَعْدَ ذَلِك أَن يُصَلِّي لَهُم فمنعوه وَأَخْبرُوهُ بِقَوْلِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَذَكَرَ ذَلِكَ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: نَعَمْ وَحَسِبْتُ أَنَّهُ قَالَ: «إِنَّكَ آذيت الله وَرَسُوله» . رَوَاهُ أَبُو دَاوُد
A man led some people in prayer and spat in the direction of the qibla. Having seen this, God’s Messenger said to the people at the end of the prayer, “He must not lead you in prayer.” The man wanted to lead them in prayer some time afterwards, but they prevented him and told him what God's Messenger had said. He mentioned that to God’s Messenger, who replied, “Yes.” And I think he added, “You have harmed God and His Messenger.’’ Abu Dawud transmitted it.
