Bulugh al-Maram 2 The Book of Prayer كتاب الصلاة 111

وَعَنْ أَنَسٍ – رضى الله عنه – قَالَ : قَالَ رَسُولُ اَللَّهِ – صلى الله عليه وسلم -{ إِذَا كَانَ أَحَدُكُمْ فِي اَلصَّلَاةِ فَإِنَّهُ يُنَاجِي رَبَّهُ , فَلَا يَبْزُقَنَّ بَيْنَ يَدَيْهِ وَلَا عَنْ يَمِينِهِ , وَلَكِنْ عَنْ شِمَالِهِ تَحْتَ قَدَمِهِ } مُتَّفَقٌ عَلَيْهِ 1 1 – صحيح . رواه البخاري (1214) ، ومسلم (551) .

Narrated Anas (RA): Allah’s Messenger (صلى الله عليه وسلم) said: “When anyone of you is engaged in Salat (prayer), he is holding intimate conversation with his Rabb so he should not spit in front of him, nor to his right side, but to his left side, under his foot”. [Agreed upon].
