ONE WHO MEMORIZES THE KORAN H 1016 "The example of one who has memorized the Koran by heart is like that of one who has a camel secured by a rope. If he watches it, he retains it; but if he neglects it, it wanders away." R 1016 Bukhari and Muslim with a chain up to ibn Omar who related that the Messenger of Allah, praise and peace be upon him, said this.
1003- وعن ابن عمر رضي الله عنهما : أنَّ رسول الله صلى الله عليه وآله وسلم ، قَالَ : "إنَّمَا مَثَلُ صَاحبِ الْقُرْآنِ كَمَثَلِ الإِبِلِ المُعَقَّلَةِ ، إنْ عَاهَدَ عَلَيْهَا أمْسَكَهَا ، وَإنْ أطْلَقَهَا ذَهَبَتْ" متفقٌ عَلَيْهِ .
