The Messenger of Allah (sal Allahu alaihi wa sallam) said: “Indeed Allah has described a parable of the Sirat Mustaqeem (Straight Path to Allah’s Pleasure and Jannah): On the two sides of the path are walls with many unlocked doors, each door having a curtain. There is a caller appointed at the head of Sirat Mustaqeem who calls out, ‘O people keep to this straight path. Don’t look at or go on the crooked paths breaking off from it.’ When a person traveling this path wishes to open one of these doors then a caller calls out, ‘Beware, do not open it. If you open it then you will adopt this path and leave the Sirat Mustaqeem.’ The Sirat Mustaqeem is Islam, and the walls are Allah’s Hudood (legal limits), and the open doors are the Haraam things forbidden by Allah, and the caller at the doors is the Quran Kareem, and the caller on the straight path is the living conscience gifted as a guide from Allah to the heart of every person possessing faith.” [Musnad Ahmed]
The Sirat Mustaqeem is the straight path that leads to Allah’s Pleasure and Jannah. It is the surest, quickest and safest way of getting there.
This hadith informs us that the conscience that Allah (subhana wa ta’ala) has gifted each human being with, is to keep us on this straight path. It keeps calling to the person reminding him/her to stick to the straight path and stay away from the things disliked by Allah (subhana wa ta’ala).
Our conscience tells us not only to not step on those paths but also not to even take a peek at them. This is because sin is tempting and many are those who will not be able to resist its pull. Once a person gets off a path, a deviation of even the slightest degree with time results in putting a great distance between the person and his/her desired destination.
The walls on the sides of the straight path are the legal limits that Allah (subhana wa ta’ala) prescribes us to stay within. The doors in the walls are the Haraam (forbidden) things that take a person off track. The Quran is another caller warning us to not open any of these forbidden doors.
