Ibn Jawzi on Hadith: How to recognize a Hadith is weak or fabricated

Ibn al-Jawzi said, “If you find a prophetic narration disagreeing with sound reason, contradicting established revelation, or conflicting with the principles, know that it is inauthentic.”

Al-Suyuti said, “The meaning of conflicting with the principles is that it falls outside the literature of Islam, the transmitted sciences and the famous books.”

قَالَ ابْنُ الْجَوْزِيِّ إِذَا رَأَيْتَ الْحَدِيثَ يُبَايِنُ الْمَعْقُولَ أَوْ يُخَالِفُ الْمَنْقُولَ أَوْ يُنَاقِضُ الْأُصُولَ فَاعْلَمْ أَنَّهُ مَوْضُوعٌ

وقال السيوطي وَمَعْنَى مُنَاقَضَتِهِ لِلْأُصُولِ أَنْ يَكُونَ خَارِجًا عَنْ دَوَاوِينِ الْإِسْلَامِ مِنَ الْمَسَانِيدِ وَالْكُتُبِ الْمَشْهُورَةِ
