Lying across in front of a praying person

 260. Aishah narrated: (And it was mentioned before her that the prayer would be nullified by a passing dog, a donkey or a woman) she said: ´´You made us equal to the dogs and asses. By Allah, I saw the Messenger of Allah salla alayhi wa sallam performing the prayer while I was lying across the bedstead between him and the Qiblah. When I felt the need, I did not like to sit (in front of him) and perturb the Messenger of Allah salla alayhi wa sallam, so I quietly moved out from the side of his legs.´´
