The Limits of the Worshipper's Sutrah

Question :

Are the edges of the carpets in the mosques considered a Sutrah for the worshipper?

Answer:

The edges of the carpets are not considered a Sutrah for the worshipper, and the Sunnah is for the Sutrah to be anything standing, such as the saddle of a camel, or something more than this, such as a wall, a pillar, a chair or the like. If he did not find any of these things, he should place a stick or some such thing in the ground in front of him, whether he be an Imam or a single worshipper. As for the one being led in prayer, the Sutrah of the Imam is a Sutrah for him. If he is in land where he can find no Sutrah, he should draw a line. All of this is based on the words of the Prophet:
"When any of you prays, he should pray towards a Sutrah and stand close to it.

And his words:
"A Muslim man's prayer is cut off by a woman, a donkey and a black dog if he does not have in front of him something such as a camel saddle.
And it was reported from him that he said:
*If any of you prays, he should place something in front of him; if he does not find anything, he should set a stick up in front of him; if he does not find (a stick), he should draw a line, then anyone who passes in front of him will not harm him.

Ibn Hajar - may Allah have mercy on him - said in Bulugh Al- Maram: "Whoever said that it is Mudhtarib is wrong, for it is Hasan." And Allah is the Granter of success.
