Musnad Ahmad 6265

Translation

✧ The Messenger of Allah ﷺ saw phlegm in the qiblah of the mosque, so he scraped it off with his hand. Then he turned to the people and was angry with them, then said: Allah, the Exalted, is in front of the face of one of you in his prayer, so let none of you spit in front of his face in his prayer.
