Passing Directly in Front of a Worshipper in the Sacred House (in Makkah)
Question :
What is the ruling on passing directly in front of a worshipper in prayer in the Sacred House (in Makkah),and is the worshipper allowed to prevent the one who tries to pass in front of him?
Answer:
There is no sin in this, and it is not allowed for someone who is in the Sacred House - I mean the Sacred Mosque - to prevent someone passing in front of him, because of the narrations which prove that the righteous Salaf, including Ibn Az-Zubair, may Allah be pleased with him, did not prevent those making Tawaf or others from passing in front of them, and because the Sacred Mosque is a place where one expects crowding and difficulty in preventing anyone passing in front of a worshipper, therefore it is obligatory to be forbearing and tolerant in this matter.
