Keep refreshing your knowledge of the Qur'an, for I swear by Him in Whose Hand is the life of Mahammad that it is more liable to escape than camels which are hobbled.
عَنِ النَّبِيِّ ﷺ قَالَ تَعَاهَدُوا هَذَا الْقُرْآنَ فَوَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَهُوَ أَشَدُّ تَفَلُّتًا مِنَ الإِبِلِ فِي عُقُلِهَا وَلَفْظُ الْحَدِيثِ لاِبْنِ بَرَّادٍ
