Ibn ‘Abdul Barr reported: Imam Malik ibn Anas, may Allah have mercy upon him, said: When the Caliph Abu Ja’far al-Mansur performed the pilgrimage, he called for me, so I entered upon him and he spoke to me, asking me questions, and I replied. Then, he said, “I am determined to have several copies made of these books of yours. I will send a copy to every region in the lands of the Muslims. I will command them to adhere to its contents without referring to any other, and they will set aside everything but this new knowledge. Indeed, I see the foundation of knowledge in the narrations of the people of Medina and their teachings.” I said, “O Commander of the Faithful, do not do so, for the people have received sayings, heard reports, and transmitted various accounts. Each one holds to what it has received and acts according to it. They practice as such due to people’s differences, the Companions of the Messenger of Allah and others. Turning them away from their beliefs would surely be difficult, so leave the people with what they are upon and what every country has chosen for themselves.” Al-Mansur said, “I swear on my life, if you had obeyed me in this matter, I would have commanded it.”

عن ابن عبد البر قال مالك بن أنس رَحِمَهُ اللَّهُ لَمَّا حَجَّ أَبُو جَعْفَرٍ الْمَنْصُورُ دَعَانِي فَدَخَلْتُ عَلَيْهِ فَحَدَّثْتُهُ وَسَأَلَنِي فَأَجَبْتُهُ فَقَالَ إِنِّي قَدْ عَزَمْتُ أَنْ آمُرَ بِكُتُبِكَ هَذِهِ الَّتِي وَضَعْتَهَا يَعْنِي الْمُوَطَّأَ فَيُنْسَخُ نُسَخًا ثُمَّ أَبْعَثُ إِلَى كُلِّ مِصْرٍ مِنْ أَمْصَارِ الْمُسْلِمِينَ مِنْهَا نُسْخَةً وَآمُرُهُمْ أَنْ يَعْمَلُوا بِمَا فِيهَا لَا يَتَعَدَّوْنَ إِلَى غَيْرِهِ وَيَدَعُونَ مَا سِوَى ذَلِكَ مِنْ هَذَا الْعِلْمِ الْمُحْدَثِ فَإِنِّي رَأَيْتُ أَصْلَ الْعِلْمِ رِوَايَةَ أَهْلِ الْمَدِينَةِ وَعِلْمَهُمْ قَالَ فَقُلْتُ يَا أَمِيرَ الْمُؤْمِنِينَ لَا تَفْعَلْ فَإِنَّ النَّاسَ قَدْ سَبَقَتْ إِلَيْهِمْ أَقَاوِيلُ وَسَمِعُوا أَحَادِيثَ وَرَوَوْا رِوَايَاتٍ وَأَخَذَ كُلُّ قَوْمٍ بِمَا سَبَقَ إِلَيْهِمْ وَعَمِلُوا بِهِ وَدَانُوا بِهِ مِنَ اخْتِلَافِ النَّاسِ أَصْحَابَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَغَيْرَهُمْ وَإِنَّ رَدَّهُمْ عَمَّا اعْتَقَدُوهُ شَدِيدٌ فَدَعِ النَّاسَ وَمَا هُمْ عَلَيْهِ وَمَا اخْتَارَ كُلُّ أَهْلِ بَلَدٍ لِأَنْفُسِهِمْ فَقَالَ لَعَمْرِي لَوْ طَاوَعْتَنِي عَلَى ذَلِكَ لَأَمَرْتُ بِهِ
