(1) بَاب النَّهْيِ عَنْ اتِّبَاعِ مُتَشَابِهِ الْقُرْآنِ وَالتَّحْذِيرِ مِنْ مُتَّبِعِيهِ وَالنَّهْيِ عَنْ الِاخْتِلَافِ فِي الْقُرْآنِ
Jundub (i. e. Ibn 'Abdullah) reported that Allah's Messenger (ﷺ) said:
Recite the Qur'an as long as your hearts agree to do so and when you find variance between them, then stand up.
