Surah Al Jathiyah Tafseer

وَإِذَا عَلِمَ مِنْ ايَاتِنَا شَيْيًا اتَّخَذَهَا هُزُوًا

And when he learns something of Our Ayat, he makes them a jest.

i.e. if he learns anything from the Qur'an, he disbelieves in it and takes it as the subject of jest and ridicule,

أُوْلَيِكَ لَهُمْ عَذَابٌ مُّهِينٌ

For such there will be a humiliating torment.

i.e. as recompense for ridiculing the Qur'an and jesting about it.

In the Sahih, Muslim recorded from Abdullah bin Umar that;

the Messenger of Allah prohibited traveling with the Qur'an to enemy lands for fear that the Qur'an might be desecrated by the enemy.

Allah explained the type of torment that these people earn on the Day of Return
