#757 It was
narrated from Hudhaifah that he saw Shabath bin Rib’i spitting
in
front of him. He said:
“O Shabath! Do not spit in front of you, for
the Messenger of Allah (ﷺ) used to forbid that, and he said: ‘When
a
man stands up to perform prayer, Allah turns His Face towards him
until he turns away or he commits an evil Hadath.’”*

* In Injah Al-Hajah, 'Abdul-Ghani Dehlawi said: "Meaning he does a matter that negates
the Khushu'(submissiveness) and attentiveness of his prayer. Or, the meaning of
Hadath is invalidating the ablution. The only reason that he described it as 'evil' is
because in most cases, its occurrence during prayer is from Shaitan."
