That is why Allah confiscated their deeds and cancelled all...
(Surah Fajr 89:27-30) Ibne Mahyar has narrated from Imam Sadiq (a.s.) that this verse was revealed in praise of Imam Husain (a.s.) and has also narrated from the same Imam that: Recite Surah Fajr in obligatory and recommended prayers because this Surah is for Imam Husain (a.s.) and take interest to recite this Surah so that Allah may have mercy on you. Abu Osama asked: How is this Surah special for Imam Husain?
The Imam replied: Have you have heard the verse: ‘ O soul that art at rest!’ It refers to Imam Husain and he is the soul at rest, who was pleased with the command of Allah and was liked by Him and his companions were from Aale Muhammad (a.s.). And Allah is pleased with him and this Surah is in the praise of Imam Husain (a.s.) and the Shias of Aale Muhammad and it is specially for them.
That is why if a person recites this Surah regularly, he will be with the Hazrat in Paradise with his position, and Allah is all powerful and wise. Kulaini and Ibne Mahyar have narrated from Sudair Sarraf that he asked Imam Sadiq (a.s.): May I be sacrificed for you, O son of the Messenger of Allah, do you feel the pains at the time of death of a believer?
The Imam replied: By Allah when the angel of death comes to a believer, he cries and is terrified, so the angel says to him: O friend of Allah, do not scream. By Allah! Who has made Muhammad a Prophet, I am more kind to you than your own father. Open your eyes and see that the Holy Prophet (S), Amirul Momineen (a.s.), Fatima, Hasan and Husain and all the Holy Imam (a.s.) come to you. The angel of death says: They all are your friends.
The believer opens his eyes and sees those blessed personages, then a callers of Allah calls his soul: O calm soul of Muhammad and his progeny, return to your Lord, and due to their Wilayat and rewards you are liked, then you be attached with my special servants.
