The following fatwa is most useful to the people who do umrah and hajj
I see most of the people doesn't take care to take sutrah for prayers in Kabah and Masjid Munawwara and many men and women cross you when you are doing salah and many think that it is Ok not to take sutrah and to cross the praying person in Kabah and Masjid Munawwara
Q7 : Is the Sutrah (waajib) compulsory in Makkah or not?
A : The Sutrah is (Waajib) compulsory in Makkah as elsewhere. There is, too, no evidence to support any differentiation between Makkah and other places. In addition, the Prophet (sallallaahu alayhi wasallam) placed a spear in front of him in the plain of Makkah (*1) and then performed Salaah-ul-Dhur and Asr. (*1) When he entered the Ka'bah too, he used its wall as a Sutrah. When he made Tawaaf around the Ka'bah, he placed the Maqaam (station) of Ibraheem between himself and it, then performed Salaah. (*2) This was what was done also, by the Sahaaba's after him.
