عَنِ ابْنِ عُمَرَ رَضِيَ اللَّه عَنْهُمَا قَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ أن يُسَافَرَ بِالْقُرْآنِ إِلَى أَرْضِ الْعَدُوِّ ((مُتَّفَقٌ عَلَيْهِ)).
Ibn 'Umar (May Allah be pleased with them) said: The Messenger of Allah (ﷺ) forbade travelling to the land of the enemy carrying the Qur'an. [Al-Bukhari and Muslim].
