Sunan Ibn Majah Book 5, Hadith 154
“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.’”
“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.”
It was narrated from Zainab bint Umm Salamah that her mother said that her bed was in front of the place where the Messenger of Allah (ﷺ) prostrated.
