[Machine] I said, "O Messenger of Allah, may I take permission to write down what I hear from you?" He said, "Yes." I asked about pleasure and anger. He said, "Yes, for it is not appropriate for me to say anything except the truth in pleasure and anger." This hadith has a sound chain of narrators, but it was not mentioned in Sahih Bukhari or Sahih Muslim.
قُلْتُ يَا رَسُولَ اللَّهِ أَتَأْذَنُ لِي فَأَكْتُبُ مَا أَسْمَعُ مِنْكَ؟ قَالَ «نَعَمْ» قُلْتُ فِي الرِّضَاءِ وَالْغَضَبِ قَالَ «نَعَمْ فَإِنَّهُ لَا يَنْبَغِي أَنْ أَقُولَ عِنْدَ الرِّضَاءِ وَالْغَضَبِ إِلَّا حَقًّا» صَحِيحُ الْإِسْنَادِ وَلَمْ يُخَرِّجَاهُ صحيح
