Sahih al-Bukhari, 531

Rapporté par Anas : Le Prophète (ﷺ) a dit : « Quand l’un de vous fait sa prière, il parle en privé avec son Seigneur. Il ne doit donc pas cracher à sa droite mais sous son pied gauche. » Qatada a dit : « Il ne doit pas cracher devant lui, mais à sa gauche ou sous ses pieds. » Et Shu`ba a dit : « Il ne doit ni cracher devant lui, ni à sa droite, mais à sa gauche ou sous son pied. » Anas a dit : Le Prophète (ﷺ) a dit : « Il ne doit ni cracher en direction de la Qibla, ni à sa droite, mais à sa gauche ou sous son pied. »

Narrated Anas:The Prophet (ﷺ) said, "Whenever anyone of you offers his prayer he is speaking in private to his Lord. So he should not spit to his right but under his left foot." Qatada said, "He should not spit in front of him but to his left or under his feet." And Shu`ba said, "He should not spit in front of him, nor to his right but to his left or under his foot." Anas said: The Prophet (ﷺ) said, "He should neither spit in the direction of his Qibla nor to his right but to his left or under his foot
