Sura al-Jumuʿah 62:5

مَثَلُ ٱلَّذِينَ حُمِّلُوا۟ ٱلتَّوْرَىٰةَ ثُمَّ لَمْ يَحْمِلُوهَا كَمَثَلِ ٱلْحِمَارِ يَحْمِلُ أَسْفَارًۢا بِئْسَ مَثَلُ ٱلْقَوْمِ ٱلَّذِينَ كَذَّبُوا۟ بِـَٔايَٰتِ ٱللَّـهِ وَٱللَّـهُ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّٰلِمِينَ

mathalu lladhīna ḥummilū l-tawrāta thumma lam yaḥmilūhā ka-mathali l-ḥimāri yaḥmilu asfāran biʾsa mathalu l-qawmi lladhīna kadhdhabū bi-āyāti allāhi wallāhu lā yahdī l-qawma l-ẓālimīna

The similitude of those who were charged with the (obligations of the) Mosaic Law, but who subsequently failed in those (obligations), is that of a donkey which carries huge tomes (but understands them not). Evil is the similitude of people who falsify the Signs of Allah: and Allah guides not people who do wrong.
