مَا نَنْسَخْ مِنْ آيَةٍ أَوْ نُنْسِهَا نَأْتِ بِخَيْرٍ...

The 6 th Imam -asws instructed a group of Suffis to learn about the abrogating and the abrogated Verses: فَتَأَدَّبُوا أَيُّهَا النَّفَرُ بِآدَابِ اللَّهِ عَزَّ وَ جَلَّ لِلْمُؤْمِنِينَ وَ اقْتَصِرُوا عَلَى أَمْرِ اللَّهِ وَ نَهْيِهِ وَ دَعُوا عَنْكُمْ مَا اشْتَبَهَ عَلَيْكُمْ مِمَّا لَا عِلْمَ لَكُمْ بِهِ وَ رُدُّوا الْعِلْمَ إِلَى أَهْلِهِ تُوجَرُوا وَ تُعْذَرُوا عِنْدَ اللَّهِ تَبَارَكَ وَ تَعَالَى (Imam Jafar e Sadiq -asws said): So educate yourselves, O group, by the Education of Allah -azwj Mighty and Majestic for the Believers, and moderate yourselves upon the Commands of Allah ‑azwj , and His -azwj Prohibitions, and leave from yourselves what is doubtful upon you, from what there is no knowledge for you of it, and refer the knowledge to its rightful ones, so you would be Recompensed, and Excused in the Presence of Allah -azwj Blessed and High.

وَ كُونُوا فِي طَلَبِ عِلْمِ نَاسِخِ الْقُرْآنِ مِنْ مَنْسُوخِهِ وَ مُحْكَمِهِ مِنْ مُتَشَابِهِهِ وَ مَا أَحَلَّ اللَّهُ فِيهِ مِمَّا حَرَّمَ فَإِنَّهُ أَقْرَبُ لَكُمْ مِنَ اللَّهِ وَ أَبْعَدُ لَكُمْ مِنَ الْجَهْلِ وَ دَعُوا الْجَهَالَةَ لِأَهْلِهَا فَإِنَّ أَهْلَ الْجَهْلِ كَثِيرٌ وَ أَهْلَ الْعِلْمِ قَلِيلٌ وَ قَدْ قَالَ اللَّهُ عَزَّ وَ جَلَّ وَ فَوْقَ كُلِّ ذِي عِلْمٍ عَلِيمٌ And become the seekers of the knowledge of the Abrogating (Verses) of the Quran from its Abrogated , and its Decisive from its Allegorical, and what Allah -azwj has Permitted regarding it from what is Prohibited.
