حَدَّثَنَا عَبْدُ الرَّحْمَنِ يَعْنِي ابْنَ مَهْدِيٍّ حَدَّثَنَا مَالِكٌ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَهَى عَنْ بَيْعِ الثَّمَرَةِ حَتَّى يَبْدُوَ صَلَاحُهَا نَهَى الْبَائِعَ وَالْمُشْتَرِيَ وَنَهَى أَنْ يُسَافَرَ بِالْقُرْآنِ إِلَى أَرْضِ الْعَدُوِّ مَخَافَةَ أَنْ يَنَالَهُ الْعَدُوُّ
مسند امام احمد بن حنبل · Hadith 4525
It was narrated from Ibn 'Umar that the Messenger of Allah (PBUH) forbade the sale of crops until they become ripe; he forbade it for the seller and the buyer. And he forbade travelling with the Qur'an to enemy lands, lest the enemy get hold of it.
