Sahih Muslim 1869a
It has been narrated on the authority of Ibn 'Umar who said: The Messenger of Allah ﷺ forbade that one should travel to the land of the enemy taking the Qur'an with him.
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ،
قَالَ نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يُسَافَرَ بِالْقُرْآنِ إِلَى أَرْضِ الْعَدُوِّ .
