question #3 Sahih al-Bukhari 6111, Book 78, Hadith 138 : How does the presence of Allah influence the behavior of a person during prayer?

While the Prophet (ﷺ) was praying, he saw sputum (on the wall) of the mosque, in the direction of the
Qibla, and so he scraped it off with his hand, and the sign of disgust (was apparent from his face) and
then said, “Whenever anyone of you is in prayer, he should not spit in front of him (in prayer) because
Allah is in front of him.”
