If he can get out of that obstacle through the good deeds which he had done, or there may be mercy from Allah which will include him, he will get out and pass that particular obstacle. The time period of keeping anyone at each of these obstacles is a thousand years. The obstacles continue, following each other; questions go on and arguments are pursued about what each station represents: the obligations and the commandments.
If one answers duly, he will pass by the last station to the abode of eternity and will be released most beautifully: He will live a perpetual life where there is neither death nor loss, and he will taste happiness where there is neither misery nor destruction. He will live beside the mercy of his Lord with the prophets, the Signs of Allah, the Truthful Ones, the ones who can intercede on behalf of others, the righteous ones whose company is truly the very best.
But if he is asked at one of the obstacles and required to make up for falling short of performing it during his lifetime, if he did not offer an act of righteousness to make up for that shortcoming, and if he is not saved through mercy from Allah Almighty that rescues him from that obstacle, his feet will slip in that area and he will fall from it into the abyss and into Hell, we seek refuge with Allah against this. All these obstacles are on the Sirat.
One of them is called the wilayat (mastership of or loyalty to the Imams from among the (ﻉ)): All people will be stopped at it and asked about the wilayat of the Commander of the Faithful Ali ibn Abu Talib and the Pure Imams after him (ﻉ). If one was observing this wilayat, adhering to it, he will pass this obstacle; otherwise, he will fall into Hell. Allah Almighty has said "But stop them, for they must be asked" (Qur'an, 37:24).
And the most important of these obstacles is the Mirsad: "For your Lord is (as a Guardian) on a watch-tower" (Qur'an, 89:14). Allah Almighty says: "By My Honor and Greatness (do I swear) that no oppression committed by an oppressor escapes My knowledge." Another obstacle is called the kinship obstacle.
Another is called amana, trust (something entrusted for safe keep to someone), another is called salat, prayer, and so on: لكل فريضه من الفرائض—الأوامر و النواهي—يوقف العبد عندها ليجيب عما هو مسؤول عنه Each obligation—what is commanded and what is prohibitive—has an obstacle at which the servant of Allah is stopped to answer about his responsibility towards it."
