Hadith 874

نَا عَبْدُ الْجَبَّارِ بْنُ الْعَلاءِ ، حَدَّثَنَا سُفْيَانُ ، عَنِ الزُّهْرِيِّ ، عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ، أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَبْصَرَ نُخَامَةً فِي قِبْلَةِ الْمَسْجِدِ فَحَكَّهَا بِحَصَاةٍ ، وَنَهَى أَنْ يَبْزُقَ الرَّجُلُ بَيْنَ يَدَيْهِ ، وَعَنْ يَمِينِهِ ، وَقَالَ : " لِيَبْزُقْ عَنْ شِمَالِهِ أَوْ تَحْتَ قَدَمِهِ الْيُسْرَى "
It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) saw phlegm towards the qiblah of the mosque, so he rubbed it and cleaned it with a pebble. And he forbade a person from spitting to his right side or in front of him (during prayer). And he said: "He should spit to his left side or under his left foot (on the unpaved ground)."
