Do you make us (women) equal to dogs and donkeys? While I used to lie in my bed, the Prophet (ﷺ) would come and pray facing the middle of the bed. I used to consider it not good to stand in front of him in his prayers. So I used to slip away slowly and quietly from the foot of the bed till I got out of my guilt.
Sahih al-Bukhari Book 8, Hadith 155
← Previous Hadith "The Prophet (ﷺ) used to make his she-camel sit across and he would pray facing it (as a Sutra)." I asked, "What would the Prophet (ﷺ) do if the she-camel was provoked and moved?" He said, "He would take its camel-saddle and put it in front of him and pray facing its back part (as a Sutra). And Ibn `Umar used to do the same." (This indicates that one should not pray except behind a Sutra).

Sahih al-Bukhari Book 8, Hadith 154 Next Hadith → The Prophet (ﷺ) said, (what is ascribed to him in the following Hadith): Narrated Abu Salih As-Samman:

I saw Abu Sa`id Al-Khudri praying on a Friday, behind something which acted as a Sutra. A young man from Bani Abi Mu'ait , wanted to pass in front of him, but Abu Sa`id repulsed him with a push on his chest. Finding no alternative he again tried to pass but Abu Sa`id pushed him with a greater force. The young man abused Abu Sa`id and went to Marwan and lodged a complaint against Abu Sa`id and Abu Sa`id followed the young man to Marwan who asked him, "O Abu Sa`id! What has happened between you and the son of your brother?" Abu Sa`id said to him, "I heard the Prophet (ﷺ) saying, 'If anybody amongst you is praying behind something as a Sutra and somebody tries to pass in front of him, then he should repulse him and if he refuses, he should use force against him for he is a Shaitan (a Satan).' "
