the Messenger of Allah said: "When you are in Salat then do not spit on your right, but behind you or toward your left, or under your left foot."
Jami` at-Tirmidhi Book 6, Hadith 28
← Previous Hadith "We were with Ibn Umar, and he said: 'The Messenger of Allah said: "Permit the women to go at night to the Masajid." His son said: 'By Allah! We would not permit them lest they become insidious from that.' So he (Abdullah) retorted: 'May Allah do and such with you.' I say: "The Messenger of Allah said," and you say: "We do not permit them?"

Jami` at-Tirmidhi Book 6, Hadith 27 Next Hadith → the Messenger of Allah said: "To spit in the Masjid is a sin, and burying it is its atonement."
