أَبِي (رحمه الله) قَالَ حَدَّثَنَا سَعْدُ بْنُ عَبْدِ اللَّهِ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ أَبِيهِ عَنْ عَلِيِّ بْنِ النُّعْمَانِ عَنْ فُضَيْلِ بْنِ عُثْمَانَ قَالَ سُئِلَ أَبُو عَبْدِ اللَّهِ (ع) فَقِيلَ لَهُ هَؤُلَاءِ الْأَخَابِثَ يَرْوُونَ عَنْ أَبِيكَ يَقُولُونَ إِنَّ أَبَاكَ (ع) قَالَ إِذَا عَرَفْتَ فَاعْمَلْ مَا شِئْتَ فَهُمْ يَسْتَحِلُّونَ بَعْدَ ذَلِكَ كُلَّ مُحَرَّمٍ قَالَ مَا لَهُمْ لَعَنَهُمُ اللَّهُ إِنَّمَا قَالَ أَبِي (ع) إِذَا عَرَفْتَ الْحَقَّ فَاعْمَلْ مَا شِئْتَ مِنْ خَيْرٍ يُقْبَلُ مِنْك 

Narrated that Abu Abdillah Imam Sadiq (ع) was asked, 

"These wicked people narrate that Your Father (ع) has said, "If you have recognized (i.e. recognized Wilayat?) then act as you wish since after having recognized (after Marefat) all the Haram acts have become permissible for you." 

Imam Sadiq (ع) replied, "May Allah curse them, rather My Father (ع) had said, "If you have recognized  (i.e. Wilayat?), then do good acts as you wish since it will be accepted from you."

أَخْبَرَنَا مُحَمَّدُ بْنُ مُحَمَّدٍ، قَالَ: أَخْبَرَنَا أَبُو غَالِبٍ أَحْمَدُ بْنُ مُحَمَّدٍ الزُّرَارِيُّ، قَالَ: حَدَّثَنَا عَبْدُ اللَّهِ بْنُ جَعْفَرٍ الْحِمْيَرِيُّ، عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ بْنِ أَبِي الْخَطَّابِ، عَنِ الْحَسَنِ بْنِ مَحْبُوبٍ، عَنْ هِشَامِ بْنِ سَالِمٍ، عَنْ عَمَّارِ بْنِ مُوسَى السَّابَاطِيِّ، قَالَ: قُلْتُ لِأَبِي عَبْدِ اللَّهِ (عَلَيْهِ السَّلَامُ): إِنَّ أَبَا أُمَيَّةَ يُوسُفَ بْنَ ثَابِتٍ حَدَّثَ عَنْكَ أَنَّكَ قُلْتَ: لَا يَضُرُّ مَعَ الْإِيمَانِ عَمَلٌ، وَ لَا يَنْفَعُ مَعَ الْكُفْرِ عَمَلٌ فَقَالَ (عَلَيْهِ السَّلَامُ): إِنَّهُ لَمْ يَسْأَلْنِي أَبُو أُمَيَّةَ عَنْ تَفْسِيرِهَا، إِنَّمَا عَنَيْتُ بِهَذَا أَنَّهُ مَنْ عَرَفَ الْإِمَامَ مِنْ آلِ مُحَمَّدٍ (عَلَيْهِمُ السَّلَامُ) وَ تَوَلَّاهُ، ثُمَّ عَمِلَ لِنَفْسِهِ بِمَا شَاءَ مِنْ عَمَلِ الْخَيْرِ قُبِلَ مِنْهُ ذَلِكَ، وَ ضُوعِفَ لَهُ أَضْعَافاً كَثِيرَةً، فَانْتَفَعَ بِأَعْمَالِ الْخَيْرِ مَعَ الْمَعْرِفَةِ، فَهَذَا مَا عَنَيْتُ بِذَلِكَ، وَ كَذَلِكَ لَا يَقْبَلُ اللَّهُ مِنَ الْعِبَادِ الْأَعْمَالَ الصَّالِحَةَ الَّتِي يَعْمَلُونَهَا إِذَا تَوَلَّوُا الْإِمَامَ الْجَائِرَ الَّذِي لَيْسَ مِنَ اللَّهِ (تَعَالَى)

فَقَالَ لَهُ عَبْدُ اللَّهِ بْنُ أَبِي يَعْفُورٍ: أَ لَيْسَ اللَّهُ (تَعَالَى) قَالَ: «مَنْ جاءَ بِالْحَسَنَةِ فَلَهُ خَيْرٌ مِنْها وَ هُمْ مِنْ فَزَعٍ يَوْمَئِذٍ آمِنُونَ» فَكَيْفَ لَا يَنْفَعُ الْعَمَلُ الصَّالِحُ مِمَّنْ تَوَلَّى أَئِمَّةَ الْجَوْرِ فَقَالَ لَهُ أَبُو عَبْدِ اللَّهِ (عَلَيْهِ السَّلَامُ): وَ هَلْ تَدْرِي مَا الْحَسَنَةُ الَّتِي عَنَاهَا اللَّهُ (تَعَالَى) فِي هَذِهِ الْآيَةِ، هِيَ وَ اللَّهِ مَعْرِفَةُ الْإِمَامِ وَ طَاعَتُهُ، وَ قَالَ (عَزَّ وَ جَلَّ): «وَ مَنْ جاءَ بِالسَّيِّئَةِ فَكُبَّتْ وُجُوهُهُمْ فِي النَّارِ هَلْ تُجْزَوْنَ إِلَّا ما كُنْتُمْ تَعْمَلُونَ» وَ إِنَّمَا أَرَادَ بِالسَّيِّئَةِ إِنْكَارَ الْإِمَامِ الَّذِي هُوَ مِنَ اللَّهِ (تَعَالَى)

ثُمَّ قَالَ أَبُو عَبْدِ اللَّهِ (عَلَيْهِ السَّلَامُ): مَنْ جَاءَ يَوْمَ الْقِيَامَةِ بِوَلَايَةِ إِمَامٍ جَائِرٍ لَيْسَ مِنَ اللَّهِ وَ جَاءَ مُنْكِراً لِحَقِّنَا جَاحِداً بِوَلَايَتِنَا، أَكَبَّهُ اللَّهُ (تَعَالَى) يَوْمَ الْقِيَامَةِ فِي النَّارِ

Narrated from Ammar al-Sabaty who said,

"I said to Abu Abdullah Imam Sadiq (ع), "Abu Umayya Yusuf Bin Sabit narrated from You that You have said, "No action/deed can cause harm with belief (Eeman) & No action/deed can be of any benefit with disbelief (Kufr)". 

Imam (ع) said, "Surely, Abu Umayya did not ask Me for its explanation. But rather what I meant by this is that one who recognizes the Imam from Aal-e-Muhammad (ع) and accepts His Wilayah, then does any good deed for himself then that deed would be accepted from him, and the good deed will be multiplied for him many times, and he would benefit with the good deed that is performed along with the recognition (Marefat). So, this is what I meant by that statement."

"And similar to that, Allah does not accept the righteous/good deeds from the servant which they perform while accepting the wilayah of the oppressive imam who isn’t appointed by Allah"

Then Abdullah Bin Abu Yafour said to the Imam (ع), "Doesn’t Allah (تعالى) say: One who comes with the good deed, for him would be better than it, and they would be secure from the panic of that Day (27:89). So, how can there be no benefit of the righteous deeds for the ones who accept the wilayah of the oppressive imams?"

Imam (ع) said, "Do you know what is the good deed that Allah is referring to in this verse? It is recognition of the Imam (ع) and obeying Him."

And Allah (عز وجل) says, "And one who comes with the evil deed, they would be thrown upon their faces into the Fire. Will you be Recompensed except for what you had been doing? (27:90). And Allah in this verse by the evil deed is referring to the denial of the Imam (ع) appointed by Allah (تعالى)."

Then Abu Abdullah (ع) said, "One whom comes on the Day of Qiyamah believing in the wilayah of an oppressive imam who isn’t from Allah and comes denying Our rights and rejecting of Our Wilayah, Allah (تعالى) would Fling him on the Day of Qiyamah into the fire."
