Umar in the Day of Judgement

بسم الله الواحد القهار

Sheikh As-Saduq:

Narrated my father(رحمه الله ) from Sa'd Ibn Abdullah from Ahmad Ibn Mohammad from Al-Hasan Ibn Ali Al-Wash'sha from Ahmad Ibn Hahiz from Abi Khadija from Abi Abdullah(عليه السلام) that he said: 
"In the Day of Judgement Shaytan will be brought with the one who misled this Ummah(i.e. Umar) chained by two tethers by the thickness of the mountain of Uhud and they will be pulled by their faces on the ground and one the doors of Hell will get closed by them."

Footnote: its chain is Sahih(authentic), its narrators are trustworthy, of the great, significant scholars.

The Religion/Beliefs through which Allah accepts our deeds

بسم الله الواحد القهار

Sheikh Hadi An-Najafi:

Al-Kulayni from Al-Husain Ibn Mohammad from Mu’alla Ibn Mohammad from al-Washsha’ from Aban from Isma’il al-Ju’fi who has said the following:

“Once a man came to abu Ja’far(عليه السلام). He had a book with him. Abu Ja’far(عليه السلام) said, ‘This is the book of a polemicist who wants to learn a religion that if followed ones deeds are accepted.’ The man said, ‘May the blessings of Allah be with you, this is exactly what I want.’ Abu Ja’far(عليه السلام) said, ‘Such religion is to testify that no one deserves to be worshipped except Allah, Who has no partners. That Mohammad(صلی الله وعليه وآله) is His servant and Messenger. And that you affirm and acknowledge that whatever he has brought is from Allah. That one has love (in his heart) for us, Ahl al-Bayt, and disassociates himself from our enemies, obeys our commands, maintains piety and humbleness in life and has hope in the rise from us of one with the Divine Authority. For us there is a government and he will establish it when Allah wills.’” 

The chain of narrators of the hadith is Sahih(authenic).

Did the Ahlulbayt(عليهم السلام) use insulting words?

بسم الله الواحد القهار

Sheikh Sayyed Mohammad Taqi Al-Musawi Al-Isfahani:

Among the traditions that indicate this is a tradition that Kulayni has mentioned in Usul Kafi through a highly authentic chain of narrators from Sadir As-Sairafi that he said: “I heard Abu Abdillah, (عليه السلام), say: ‘In the Master of this affair there is a likeness to Yusuf, (عليه السلام).’ “He said: “I said to him: ‘You must be referring to [al-Mahdi], but to his life or his occultation?’ 
“He said: “Then he said to me: ‘Which does this swine-like Ummah deny? The brothers of Yusuf, (عليه السلام), were descendants of prophets; they made a business of Yusuf, then they traded with him and spoke with him, and they were his brothers and he was their brother; but they did not know who he was until he said: “I am Yusuf and this is my brother.”[12:90] 
So why does this cursed Ummah deny that Allah, to whom belong Might and Majesty, can do with His Divine Proof at some time or other what he did with Yusuf? Yusuf, (عليه السلام), held sovereignty over Egypt and between him and his father there was an eighteen day journey; if he had wanted to let [his father] know he would have done so. But Yaqoob, (عليه السلام), and his sons, on [hearing] the good news, traveled the distance from their desert to Egypt in nine days. So how can this group deny that Allah, to Whom belong Might and Majesty, can do with his Divine Proof what he did with Yusuf? He will [come and] go in their markets and step on their rugs [i.e., enter their homes] until Allah to whom belong Might and Majesty, gives him leave in this matter; just as He gave Yusuf leave and they said: “Why, are you indeed Yusuf?” “I am Yusuf,” he said.[12:90]
