[Machine] When Abu Salamah arrived in Basrah, both Hassan and I went to visit him. He said to Hassan, "Are you Hassan? No one in Basrah is dearer to me for a meeting than you. This is because I heard that you give fatwas based on your opinion, but do not give fatwas based on your opinion unless it is a Sunnah from the Messenger of Allah ﷺ or a revealed book."
لَمَّا قَدِمَ أَبُو سَلَمَةَ الْبَصْرَةَ أَتَيْتُهُ أَنَا وَالْحَسَنُ فَقَالَ لِلْحَسَنِ أَنْتَ الْحَسَنُ؟ «مَا كَانَ أَحَدٌ بِالْبَصْرَةِ أَحَبَّ إِلَيَّ لِقَاءً مِنْكَ وَذَلِكَ أَنَّهُ بَلَغَنِي أَنَّكَ تُفْتِي بِرَأْيِكَ فَلَا تُفْتِ بِرَأْيِكَ إِلَّا أَنْ تَكُونَ سُنَّةٌ عَنْ رَسُولِ اللَّهِ ﷺ أَوْ كِتَابٌ مُنْزَلٌ»
