وَعَنْهُ أَيْضًا أَنَّ نَبِيَّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((إِذَا كَانَ أَحَدُكُمْ فِي الصَّلَاةِ فَإِنَّهُ مُنَاجٍ رَبَّهُ، فَلَا يَتْفُلَنَّ أَحَدٌ مِنْكُمْ عَنْ يَمِينِهِ، قَالَ ابْنُ جَعْفَرٍ: فَلَا يَتْفُلْ أَمَامَهُ وَلَا عَنْ يَمِينِهِ، وَلَكِنْ عَنْ يَسَارِهِ أَوْ تَحْتَ قَدَمَيْهِ))
It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: When any one of you is in prayer, he is whispering to his Lord, so no person should spit to his right side. The words of Ibn Ja'far's narration are: He should not spit in front of him or to his right side, but should spit to his left side or beneath his feet.
