Sunan Ibn Majah Book 5, Hadith 153
“When anyone of you is performing prayer, he should not
let anyone pass in front of him. If he insists then let him fight
him,
for he has a Qarin (devil-companion) with him.”
“The Messenger of Allah (ﷺ) said: ‘When anyone of you performs prayer, let him pray facing towards a Sutrah, and let him get close to it, and not let anyone pass in front of him. If someone comes and wants to pass in front of him, let him fight him, for he is a Shaitan (satan).’”
“The Prophet (ﷺ) used to pray at night, and I was laying between him and the prayer direction, as a (body for a) funeral horizontally.’”
