[Machine] I heard Imam Shafi'i say, "I approve the testimony of all the people of desires except for the Rafidites, as some of them testify for each other." The sheikh, may Allah have mercy on him, said, "This also applies to whoever is known from among them to insult the companions who are the pillars of this nation and its chest. His testimony is not accepted whenever his insult to them is based on bigotry or ignorance, not on interpretation or uncertainty."  

سَمِعْتُ الشَّافِعِيَّ يَقُولُ أُجِيزُ شَهَادَةَ أَهْلِ الْأَهْوَاءِ كُلِّهِمْ إِلَّا الرَّافِضَةَ فَإِنَّهُ يَشْهَدُ بَعْضُهُمْ لِبَعْضٍ قَالَ الشَّيْخُ رَحِمَهُ اللهُ وَكَذَلِكَ مَنْ عُرِفَ مِنْهُمْ بِسَبِّ الصَّحَابَةِ الَّذِينَ هُمْ سُرُجُ هَذِهِ الْأُمَّةِ وَصَدْرُهَا لَمْ تُقْبَلْ شَهَادَتُهُ مَتَى مَا كَانَ سَبُّهُ إِيَّاهُمْ عَلَى وَجْهِ الْعَصَبِيَّةِ أَوِ الْجَهَالَةِ لَا عَلَى تَأْوِيلٍ أَوْ شُبْهَةٍ
