"The likeness of the Quran is that of a hobbled camel. If its owner ties its rope, he will keep it, but if he loosens its rope it will go away." (Using translation from Ibn Mājah 3783)
قَالَ رَسُولُ اللهِ ﷺ مَثَلُ الْقُرْآنِ مَثَلُ الْإِبِلِ الْمُعَقَّلَةِ إِنْ تَعَاهَدَهَا صَاحِبُهَا أَمْسَكَهَا وَإِنْ تَرَكَهَا ذَهَبَتْ
