1. d ibn Sinan from ‘Ammar ibn Marwan from Jabir who has said the following. “Abu Ja‘far (a.s.) has said that the Messenger of Allah has said, ‘The Hadith (statements) of Ahl al-Bayt (members of the family of Prophet Muhammad) is difficult and it becomes difficult. No one believes in it except the angels that are close to Allah or the Prophets who are Messengers also, a servant of Allah whose He has tested for faith. Whatever would come to you of the Hadith (statements) of Ahl al-Bayt of Muhammad (members of the family of Prophet Muhammad), if your heart would feel relief and you recognized them accept them. Whatever that would cause antipathy in your hearts and you could not recognize leave them to Allah, to the Messenger of Allah and the scholar from Ahl al-Bayt of Muhammad. The ones to perish are those who do not accept Hadith of Ahl al-Bayt (members of the family of Prophet Muhammad).Whenever one is narrated to them they say, “By Allah, this was not and that was not.” Denial is disbelief.”

2. Ahmad ibn ’Idris has narrated from ‘Imran ibn Musa from Harun ibn Muslim from Mas‘ada ibn Sadaqa who has said the following. “I said to abu ‘Abdallah that I one day spoke of Taqiya (hiding something for fear) before Ali ibn al-Husayn (a.s.).” He said, “By Allah, if abu Dhar knew what was in the heart of Salam he would have killed him even though the Messenger of Allah had formed brotherhood between them. What then would you think of the rest of the people? The knowledge of the scholars is difficult and it becomes difficult No one is capable to bear it except a prophet who is a messenger also or an angel who is close to Allah or a believer whose heart Allaah has tested for faith.” The Imam (a.s.) then said, “The only reason that Salman became of the scholars is because he is a man from us (Ahl al-Bayt). For this reason, I ascribed him to the scholars.”

3. Ali ibn Ibrahim has narrated from his father from al-Barqi from ibn Sinan or others in a marfu‘ manner from abu ‘Abdallah (a.s.) who has said the following. “Our Hadith (statements) are difficult and they become difficult. Only well lighted chests, the well protected of virtuous moral abilities are capable to accept them.” Allah has taken a pledge from our Shi‘a (followers) just as He has taken such pledge from the children of Adam (Am I not Your Lord?” Whoever would remain loyal to us Allah will grant then paradise. Whoever would dislike us and would not deliver our rights to us they will live in fire forever.”

4. Muhammad ibn Yahya and others have narrated from Muhammad ibn Ahmad from one of our people the following. “I wrote to Imam al-Hassan al_’Askari (a.s.) saying, May Allah take my soul in service for your cause, what is the meaning of the following Hadith of Imam Ja‘far al-Sadiq (a.s.)? “Our Hadith (statements) are difficult and they become difficult. No one is capable to bear them not even an angel or a prophet who is also a messenger or a believer whose heart Allah has tested for faith.?” The answer came as herein below. “The meaning of the words the truthful one ‘that angels, prophets and believers are not capable to accept them’ is that of the truthful one is that the angel does bear it until he deliver it to other angels. The prophet does noor bear it until he delivers it to another prophet and the believer does not bear it until he delivers to another believer. This is the meaning of the words of my grandfather.”
