Hadith 1:

قال رسول الله ص طوبى لمن أدرك قائم أهل بيتي و هو يأتم به في غيبته قبل قيامه و يتولى أولياءه و يعادي أعداءه ذلك من رفقائي و ذوي مودتي و أكرم أمتي علي يوم القيامة

The Messenger of Allah (saww) said:

"Bliss be for the person who will be in the time of the Qa'im of my Household, who follows the Qa'im during his occultation before his rise and loves his lovers and has enmity with his enemies. Such a person is of my friends and lovers and he is the most honorable of my Ummah to me on the Day of Judgment."

Hadith 2:

قال رسول الله ص طوبى لمن أدرك قائم أهل بيتي و هو مقتد به قبل قيامه يأتم به و بأئمة الهدى من قبله و يبرأ إلى الله عز و جل من عدوهم أولئك رفقائي و أكرم أمتي علي‏

Messenger of Allah (saww) said:

"Bliss be for the one who will be in the time of the Qa'im of my household, who will be his follower before his rise, and will follow him and the Imams of Guidance before him, and turns away to Allah with tabarrah from their enemies. They are my friends and the most honorable of my Ummah to me."

Hadith 3:

أبيه أمير المؤمنين علي بن أبي طالب ع أنه قال التاسع من ولدك يا حسين هو القائم بالحق المظهر للدين و الباسط للعدل قال الحسين فقلت له يا أمير المؤمنين و إن ذلك لكائن فقال ع إي و الذي بعث محمدا ص بالنبوة و اصطفاه على جميع البرية و لكن بعد غيبة و حيرة فلا يثبت فيها على دينه إلا المخلصون المباشرون لروح اليقين الذين أخذ الله عز و جل ميثاقهم بولايتنا و كتب في قلوبهم الإيمان و أيدهم بروح منه

Narrated from Ameerul Momineen (as), that he said to Husain (as):

The ninth from your sons, O’ Husain (as), is the Establisher of the Truth (al-Qa-'im bil-Haqq), the Mahzer (manifestation) of the Religion, and the Deliverer of Justice.”

Husain (a.s) says, “I said, O’ Ameerul Momineen (a.s), is that to happen?” He said, “Verily so, by the One Who sent Muhammad (saw) with Prophet hood and chose him over all of creation! It will happen, however, after an occultation and a bewilderment in

which no one remains on his religion but the sincere ones who are touched by the spirit of certainty, people from whom Allah has taken their covenant for our guardianship (Wilayat) and has inscribed faith in their hearts and has endorsed them with a spirit from Himself.”

Hadith 4:

حدثنا أحمد بن زياد بن جعفر الهمداني رضي الله عنه قال: حدثنا علي ابن إبراهيم بن هاشم، عن أبيه، عن صالح بن السندي، عن يونس بن عبدالرحمن قال: دخلت على موسى بن جعفر عليهما السلام فقلت له: ياابن رسول الله أنت القائم بالحق؟ فقال: أنا القائم بالحق ولكن القائم الذي يطهر الارض من أعداء الله عزوجل ويملا ها عدلا كماملئت جورا وظلما هو الخامس من ولدي له غيبة يطول أمدها خوفا على نفسه، يرتد فيها أقوام ويثبت فيها آخرون ثم قال: طوبى لشيعتنا، المتمسكين بحبلنا في غيبة قائمنا، الثابتين على موالاتنا والبراء ة من أعدائنا، أولئك منا ونحن منهم، قد رضوا بنا أئمة، ورضينا بهم شيعة، فطوبى لهم، ثم طوبي لهم، وهم والله معنا في درجاتنا يوم القيامة

Narrated from Yunus bin Abdur Rahman that he said: I came to Musa bin Jafar (عليه السلام) and asked him:

"O son of Allah’s Messenger! Are you the Qaim bil Haqq (the one who will rise with truth)? 

Imam (عليه السلام) replied, "I am Qaim bil Haqq, but the Qaim who shall purify the earth from the enemies of Allah Almighty and who shall fill it with justice in the same way as it would be filled with injustice and oppression, is my fifth descendent who will have a prolonged occultation (Ghaybah) because his life shall be in danger. During this period (of occultation) some people will deviate from the truth and some would remain steadfast on it."

Then the Imam (عليه السلام) said, "Blessed are those of our Shias who during the occultation of Our Qaim (عليه السلام) remain attached to Our Wilayat (guardianship) and who are steadfast in Our love (Mawalaat) and steadfast in staying clear (Baraat) from Our enemies. They are from Us and We are from them. And indeed they have acceptes Us as Imams and We have also accepted them as Our followers (Shia). Blessed are they and blessed are they (i.e. Shias). By Allah, on the Day of Judgment they shall be with Us in Our stations."
