In-book no 4706وَحَدَّثَنَا 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 .
It has been narrated on the authority of Ibn 'Umar that the Messenger of Allah (ﷺ) 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.
