السلام عليكم
The Shia narrations prove without the shadow of a doubt that the infallible Shia Imams are a source of misguidance to their own followers before anyone else, let’s see why with our own eyes from al-Kafi …

أَحْمَدُ بْنُ إِدْرِيسَ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنِ الْحَسَنِ بْنِ عَلِيٍّ عَنْ ثَعْلَبَةَ بْنِ مَيْمُونٍ عَنْ زُرَارَةَ بْنِ أَعْيَنَ عَنْ أَبِي جَعْفَرٍ ( عليه السلام ) قَالَ سَأَلْتُهُ عَنْ مَسْأَلَةٍ فَأَجَابَنِي ثُمَّ جَاءَهُ رَجُلٌ فَسَأَلَهُ عَنْهَا فَأَجَابَهُ بِخِلَافِ مَا أَجَابَنِي ثُمَّ جَاءَ رَجُلٌ آخَرُ فَأَجَابَهُ بِخِلَافِ مَا أَجَابَنِي وَ أَجَابَ صَاحِبِي فَلَمَّا خَرَجَ الرَّجُلَانِ قُلْتُ يَا ابْنَ رَسُولِ اللَّهِ رَجُلَانِ مِنْ أَهْلِ الْعِرَاقِ مِنْ شِيعَتِكُمْ قَدِمَا يَسْأَلَانِ فَأَجَبْتَ كُلَّ وَاحِدٍ مِنْهُمَا بِغَيْرِ مَا أَجَبْتَ بِهِ صَاحِبَهُ فَقَالَ يَا زُرَارَةُ إِنَّ هَذَا خَيْرٌ لَنَا وَ أَبْقَى لَنَا وَ لَكُمْ وَ لَوِ اجْتَمَعْتُمْ عَلَى أَمْرٍ وَاحِدٍ لَصَدَّقَكُمُ النَّاسُ عَلَيْنَا وَ لَكَانَ أَقَلَّ لِبَقَائِنَا وَ بَقَائِكُمْ قَالَ ثُمَّ قُلْتُ لِأَبِي عَبْدِ اللَّهِ ( عليه السلام ) شِيعَتُكُمْ لَوْ حَمَلْتُمُوهُمْ عَلَى الْأَسِنَّةِ أَوْ عَلَى النَّارِ لَمَضَوْا وَ هُمْ يَخْرُجُونَ مِنْ عِنْدِكُمْ مُخْتَلِفِينَ قَالَ فَأَجَابَنِي بِمِثْلِ جَوَابِ أَبِيهِ .

Ahmad ibn Idris from Muhamad ibn ‘Abdul-Jabbar from al-Hassan ibn ‘Ali from Tha’alabah ibn Maymoun from Zurarah ibn A’ayun that he said: I asked Imam al-Baqir (as) a question so the Imam gave me the answer then another man came and asked the same question so the Imam gave him a different answer, then another one came and asked about it so the Imam gave him a completely different answer than both of us. when both men left I asked the Imam: “O son of Rassul Allah, two men from ‘Iraq and from your Shia came to ask you but you gave each of them different answers.” He replied: “O Zurarah, this is good for us so that we may remain safer because if you all agree on this then the people will believe in it and they would be guided to us but we will not remain for long.”
Later I said to his son al-Sadiq (as): “Your Shia always walk away from you with different opinions and answers” so he gave me the same reply as his father.

al-Behbudi said: Sahih.

عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي نَجْرَانَ عَنْ عَاصِمِ بْنِ حُمَيْدٍ عَنْ مَنْصُورِ بْنِ حَازِمٍ قَالَ قُلْتُ لِأَبِي عَبْدِ اللَّهِ ( عليه السلام ) مَا بَالِي أَسْأَلُكَ عَنِ الْمَسْأَلَةِ فَتُجِيبُنِي فِيهَا بِالْجَوَابِ ثُمَّ يَجِيئُكَ غَيْرِي فَتُجِيبُهُ فِيهَا بِجَوَابٍ آخَرَ فَقَالَ إِنَّا نُجِيبُ النَّاسَ عَلَى الزِّيَادَةِ وَ النُّقْصَانِ قَالَ قُلْتُ فَأَخْبِرْنِي عَنْ أَصْحَابِ رَسُولِ اللَّهِ ( صلى الله عليه وآله ) صَدَقُوا عَلَى مُحَمَّدٍ ( صلى الله عليه وآله ) أَمْ كَذَبُوا قَالَ بَلْ صَدَقُوا قَالَ قُلْتُ فَمَا بَالُهُمُ اخْتَلَفُوا فَقَالَ أَ مَا تَعْلَمُ أَنَّ الرَّجُلَ كَانَ يَأْتِي رَسُولَ اللَّهِ ( صلى الله عليه وآله ) فَيَسْأَلُهُ عَنِ الْمَسْأَلَةِ فَيُجِيبُهُ فِيهَا بِالْجَوَابِ ثُمَّ يُجِيبُهُ بَعْدَ ذَلِكَ مَا يَنْسَخُ ذَلِكَ الْجَوَابَ فَنَسَخَتِ الْأَحَادِيثُ بَعْضُهَا بَعْضاً .

‘Ali ibn Ibrahim from his father from ibn abi Najran from ‘Assim bin Humayd from Mansour ibn Hazim who said: I said to al-Sadiq (as): “What is the matter with you, I ask a question and you give me an answer then another man comes and asks it so you give him a completely different one?” The Imam replied: “we answer people in matters of addition and deletion.” I said to him: “Then tell me about the companions of Rassul-Allah SAWS do they narrate truthful narrations or do they lie?” the Imam said: “They are truthful” I asked: “Why did they differ?” he replied: “Do you not know that a man used to come to Rassul-Allah SAWS and ask a question then he answers him but later he would answer to the same question differently because the Ahadith they abrogate each other.”

al-Majlisi said: Hasan.

I ask were the Ahadith still being abrogated during the time of the Imams? we leave the answers to the practitioners of Taqqiyah.
