(1) بَاب النَّهْيِ عَنْ اتِّبَاعِ مُتَشَابِهِ الْقُرْآنِ وَالتَّحْذِيرِ مِنْ مُتَّبِعِيهِ وَالنَّهْيِ عَنْ الِاخْتِلَافِ فِي الْقُرْآنِ
Jundub b. 'Abdullah al-Bajali reported Allah's Messenger (ﷺ) as saying:
Recite the Qur'an as long as your hearts agree to do so, and when you feel variance between them (between your hearts and tongues), then get up (and leave its recital for the time being).
