Ibn Majah

Benefits and Issues:
➊
When a person is praying in a place where there is a likelihood of people passing in front of him, it is Sunnah to place a sutrah (barrier) in front of him.

➋
What kind of sutrah should it be, and how high should it be? This is determined by this hadith: it should be as high as the rear part of a camel’s saddle. This is approximately one and a quarter to one and a half feet. Accordingly, the sutrah should be at least one and a quarter to one and a half feet high.

➌
This indicates that if someone passes in front of the person praying, his prayer will be affected. Some scholars have interpreted this to mean that it affects the humility and concentration (khushu‘ and khudu‘) in prayer. When there is a sutrah, the attention of the person praying remains confined to a limited space. In Sahih Muslim, the Prophet’s (sallallahu alayhi wa sallam) statement is: “The prayer of one who prays without a sutrah is broken by the passing of a woman, a donkey, and a black dog.” (Sahih Muslim, Salat, Chapter: The extent of what should screen the one who prays, Hadith: 510)
In Sunan Ibn Majah (Hadith: 949), the words “al-mar’ah al-ha’id” (a menstruating woman) are used. By this is meant an adult woman. It is possible that it means if a woman is menstruating and passes in front, the prayer is broken, otherwise not; but the first meaning appears more correct. And Allah knows best.

➍
Shaykh Ahmad Shakir rahimahullah (of Egypt) has considered the hadith in Sunan Abu Dawud (“Nothing breaks the prayer”) (Sunan Abu Dawud, Salat, Chapter: Whoever said nothing breaks the prayer, Hadith: 719) as abrogating all these ahadith. He further said that the narration in (Sunan Daraqutni: 3/367 and Sunan al-Kubra by al-Bayhaqi: 2/278) supports this view. For details, see: (Jami‘ at-Tirmidhi, Salat, Chapter: What has been reported that nothing breaks the prayer except a dog, a donkey, and a woman, Hadith: 338, footnote by Shaykh Ahmad Shakir rahimahullah).

➎
The purpose of the sutrah is that if someone wants to pass, he should pass beyond the sutrah and not between the sutrah and the person praying.

Hadith Commentary: Benefits and Issues:
➊
The Messenger of Allah (sallallahu alayhi wa sallam) is extremely merciful and compassionate towards his ummah, and he would supplicate with weeping and lamentation before Allah Almighty for the salvation of his ummah.
➋
The status and rank of the Prophet (sallallahu alayhi wa sallam) before Allah Almighty is exceedingly lofty and exalted. When he (sallallahu alayhi wa sallam) wept at the thought of his ummah being held accountable for their sins, Allah immediately sent Jibril (alayhis salam) to inquire about the reason for his weeping, even though Allah Almighty was fully aware of the reason.
➌
Raising the hands is also included among the etiquettes of supplication (du'a).
➍
For the sinners of the ummah, this is an extremely hopeful matter, rather, it is a great glad tiding that the blessed verse, ﴿وَلَسَوْفَ يُعْطِيكَ رَبُّكَ فَتَرْضَىٰ﴾ "And your Lord is going to give you, and you will be satisfied," is also related to the Hereafter. Allah Almighty will not only make the Prophet (sallallahu alayhi wa sallam) pleased regarding his ummah, but He will also protect him (sallallahu alayhi wa sallam) from grief and sorrow. And this will only happen when all individuals of his ummah attain salvation. If any individual from his ummah remains in Hell due to his sins, then this would be a cause of distress for him (sallallahu alayhi wa sallam).

685. Commentary:
It is understood that not placing a sutrah causes harm to the one praying. That is, there is a decrease in his humility, submissiveness, and reward, or at the very least, the harm of falling short in following the command is evident. And this sutrah should be something at least between one foot to one and a half feet in height.
