Sahih Muslim , Book 33, Hadith 137 (In-Book) ⓘ

It has been narrated on the authority of Ibn 'Umar that the Messenger of Allah said: Do not take the Qur'an on a journey with you, for I am afraid lost it should fall into the hands of the enemy. Ayyub (one of the narrators in the chain of transmitters) said: The enemy may seize it and may quarrel with you over it.

وَحَدَّثَنَا أَبُو الرَّبِيعِ الْعَتَكِيُّ، وَأَبُو كَامِلٍ قَالاَ حَدَّثَنَا حَمَّادٌ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ لاَ تُسَافِرُوا بِالْقُرْآنِ فَإِنِّي لاَ آمَنُ أَنْ يَنَالَهُ الْعَدُوُّ ‏" ‏ ‏.‏ قَالَ أَيُّوبُ فَقَدْ نَالَهُ الْعَدُوُّ وَخَاصَمُوكُمْ بِهِ ‏.‏
