Surah Al-Jumu'a, Verse 5
مَثَلُ ٱلَّذِينَ حُمِّلُوا۟ ٱلتَّوْرَىٰةَ ثُمَّ لَمْ يَحْمِلُوهَا كَمَثَلِ ٱلْحِمَارِ يَحْمِلُ أَسْفَارًۢا ۚ بِئْسَ مَثَلُ ٱلْقَوْمِ ٱلَّذِينَ كَذَّبُوا۟ بِـَٔايَٰتِ ٱللَّهِ ۚ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّٰلِمِينَ
Translation — Sahih International
The example of those who were entrusted with the Torah and then did not take it on is like that of a donkey who carries volumes [of books]. Wretched is the example of the people who deny the signs of Allah. And Allah does not guide the wrongdoing people.
