Narrated Ibn `Umar:The Prophet (ﷺ) saw some sputum on the wall facing the Qibla of the mosque and became furious with the people of the mosque and said, "During the prayer, Allah is in front of everyone of you and so he should not spit (or said, 'He should not expectorate')." Then he got down and scratched the sputum with his hand. Ibn `Umar said (after narrating), "If anyone of you has to spit during the prayer, he should spit to his left
Ibn Umar (رضی اللہ عنہما) bataate hain: Nabi ne masjid ki Qibla wali deewar par thook dekha aur masjid walon par gussa hue, aur farmaya: "Namaz mein, Allah tum mein se har ek ke saamne hota hai, isliye koi na thooke (ya kaha, use thookna nahi chahiye)." Phir Aap utre aur apne haath se thook khurach diya. Ibn Umar ne (yeh bayan karne ke baad) kaha: "Agar tum mein se kisi ko namaz mein thookna ho, use apne baayen taraf thookna chahiye."
