Salaam Friend,
thank you for the post.
well... i'm not really sure what i mean, since the term is a bit vague for me still. i searched for the term and i found this, which seems to be applicable:
Abu Sa'id reports that the Prophet

said:
"When one of you prays, he should pray toward his sutrah and he should be close to it." This is related by Abu Dawud and Ibn Majah.
Ibn 'Umar relates that "
when the Prophet
went out to pray salatul 'id, he asked for a spear and placed it in front of himself and he offered salah toward it and the people prayed behind him. And he would do that while he was traveling so that those in authority [for the affairs of the Muslims] would also do this." This is related by al-Bukhari, Muslim, and Abu Dawud.
Sabrah ibn Mu'abid reports that the Messenger of Allah

said: "
When one of you prays, he should make a partition for his salah, even if it is an arrow." This is related by Ahmad and by al-Hakim who said it is sahih according to the criteria of Muslim. Al-Haithami observes: "Ahmad's narrators are sound."
Abu Hurairah relates that the Prophet said:
"When one of you prays, he should place something in front of him. If he cannot find anything, he should prop up his staff [in front of him]. If he does not have a staff, he should draw a line [on the ground in front of him] then nothing that passes in front of him will harm him." This is related by Ahmad and Abu Dawud and Ibn Hibban. The later classifies it sahih as did Ahmad and Ibn al-Madini. Al-Baihaqi says: "There is no problem with that hadith regarding that ruling, Allah willing."
Talhah says: "We used to pray and the animals would pass in front of us. We mentioned that to the Prophet and he said: "If anything the size of a saddle is in front of you, nothing that passes beyond it would harm you." [This is related by Ahmad, Muslim, Abu Dawud, Ibn Majah, and at-Tirmidhi who calls it hasan sahih]
(bold added by me for emphasis)
hmm... so, if i read your response correct, you are saying that Sutrah is more of an injunction to have something in front of you whilst you are praying, is that correct?
