Yunus al-Sadafi reported: I have not seen anyone wiser than Al-Shafi’i, may Allah be pleased with him. I debated him one day over an issue, and then we separated. He later met me and took my hand, then he said, “O Abu Musa, can we not continue to be brothers, even if we disagree on an issue?”

عن يونس الصدفي مَا رَأَيْتُ أَعْقَلَ مِنَ الشَّافِعِيِّ رضي الله عنه نَاظَرْتُهُ يَوْمًا فِي مَسْأَلَةٍ ثُمَّ افْتَرَقْنَا وَلَقِيَنِي فَأَخَذَ بِيَدِي ثُمَّ قَالَ يَا أَبَا مُوسَى أَلَا يَسْتَقِيمُ أَنْ نَكُونَ إِخْوَانًا وَإِنْ لَمْ نَتَّفِقْ فِي مَسْأَلَةٍ
