Yes, it not just the Wahhabis who call the Rafidha what they are i.e. Rafidah.

It was narrated by Kulayni in his al-Kafi 1/174, and authenticated both by Majlisi and Bahbude:

5 – عدة من اصحابنا، عن أحمد بن محمد بن عيسى، عن على بن الحكم، عن أبان قال: أخبرني الاحول أن زيد بن علي بن الحسين (عليهما السلام) بعث اليه وهو مستخف قال: فأتيته فقال لي: يا أبا جعفر ما تقول ان طرقك طارق منا أتخرج معه؟ قال:
فقلت له: إن كان أباك أو أخاك، خرجت معه قال: فقال لي: فأنا أريد أن أخرج أجاهد هؤلاء القوم فأخرج معى قال: قلت: لا ما افعل جعلت فداك، قال: فقال لي: أترغب بنفسك عني؟ قال: قلت له: إنما هى نفس واحدة فان كان لله في الارض حجة فالمتخلف عنك ناج والخارج معك هالك وان لا تكن لله حجة في الارض فالمتخلف عنك والخارج معك سواء.
قال: فقال لي: يا أبا جعفر كنت أجلس مع أبي على الخوان فيلقمني البضعة السمينة ويبرد لي اللقمة الحارة حتى تبرد، شفقة علي، ولم يشفق علي من حر النار، إذا أخبرك بالدين ولم يخبرني به؟ فقلت له: جعلت فداك شفقته عليك من حر النار لم يخبرك، خاف عليك: أن لا تقبله فتدخل النار، وأخبرني أنا، فإن قبلت نجوت، وإن لم أقبل لم يبال أن أدخل النار، ثم قلت له: جعلت فداك أنتم أفضل أم الانبياء؟ قال: بل الانبياء قلت: يقول يعقوب ليوسف: يا بني لا تقصص رؤياك على إخوتك فيكيدوا لك كيدا، لم لم يخبرهم حتى كانوا لا يكيدونه ولكن كتمهم ذلك فكذا أبوك كتمك لانه خاف عليك، قال: فقال: أما والله لئن قلت ذلك لقد حدثني صاحبك بالمدينة أني اقتل واصلب بالكناسة وأن عنده لصحيفة فيها قتلي وصلبي.
فحججت فحدثت أبا عبدالله (عليه السلام) بمقالة زيد وما قلت له، فقال: لي: أخذته من بين يديه ومن خلفه وعن يمينه وعن شماله ومن فوق رأسه ومن تحت قدميه، ولم تترك له مسلكا يسلكه.

A number of our people has narrated from Ahmad ibn Muhammad ibn ‘isa from Ali ibn al-Hakam from Aban which narrated from al-Ahwal that Zayd ibn Ali ibn al-Husayn (alaihi salam) sent for him …

when he was in hiding. When I met him, Zayd said, “O abu Ja‘far, what would say if someone will from us would come to you asking to join us? Will you rise up with him (against the enemies)?” I said, “Would it be your father or brother I would have joined them.” He then said, “I want to rise up against these people. Come and join me.” I then said, “No, may Allah my soul of service to you.” He then said, “Is it that you keep yourself away from me?” I said, ” It is only one soul. If Allah’s authority on earth exists, then those keeping away from you would have saved themselves and those joining you would have faced their destruction. If there would Divine authority exist one earth then people joining and keeping away from would be the same.” He then said, “O abu Ja‘far, I would sit with my father at the same table he would feed me chunky morsels and cool off for me the hot one out kindness and diligent care. Do you think he was not afraid for me from the fire of hell? So he has informed you about religion and did not inform me?” I said, ” May Allah make my soul of service to you, it is also because of the kindness of your father to you that to save you from the fire he did not inform you. He was afraid for you that after having the information you would ignore his guidance and so you become subject of fire He informed me also and if I would follow I will be safe and become destroyed if disobeyed for he which he was not that much concerned. Then I told him, “..” May Allah make my soul of service to you, are you of a higher degree of excellence or the prophets?” He said, “It is the prophets.” I said, “Consider that Ya‘qub has said to Joseph, ‘My son do not tell your dream to your brothers. They may plot against you. Why he not inform the brothers so that they would not plot against Josephe?.He hid it from them such the way your father has done because he was afraid about you.” Then He said, “When you say that, I swear to Allah that your friend (the Imam (a.s.) told me in Madina that I will be killed and crucified in al-Kunnasa and that he has a book with him that lists the people killed and crucified.” I then went for Hajj and reported the story of Zayd to abu ‘Abdallah (a.s.) and what I said to Zayd. The Imam (a.s.) said, “You surrounded him from his fron, back, left, right, above and below and did not leave for any way out.

We have some important proofs in this text. Divine authority is nothing but myth. Because if it wouldn’t be a myth, imam Ali ibn Husayn would for sure explain it to his son. Imamate, it’s importance, appointment of 12 imams is also fairy tale. Shia claim that this institute of Imamate was well known, explained, but in this hadith we have proof that even son of the Imam didn’t know this shia pillar.
