Sahih al-Bukhari 412

حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ أَخْبَرَنِي قَتَادَةُ، قَالَ سَمِعْتُ أَنَسًا، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ لاَ يَتْفِلَنَّ أَحَدُكُمْ بَيْنَ يَدَيْهِ وَلاَ عَنْ يَمِينِهِ، وَلَكِنْ عَنْ يَسَارِهِ أَوْ تَحْتَ رِجْلِهِ ‏"‏‏.‏

Narrated Anas:The Prophet (ﷺ) said, "None of you should spit in front or on his right but he could spit either on his left or under his foot
