مَثَلُ الَّذِيْنَ حُمِّلُوا التَّوْرٰىةَ ثُمَّ لَمْ يَحْمِلُوْهَا كَمَثَلِ الْحِمَارِ يَحْمِلُ اَسْفَارًاۗ بِئْسَ مَثَلُ الْقَوْمِ الَّذِيْنَ كَذَّبُوْا بِاٰيٰتِ اللّٰهِ ۗوَاللّٰهُ لَا يَهْدِى الْقَوْمَ الظّٰلِمِيْنَ ( الجمعة: ٥ )
Masalul lazeena hum milut tawraata summa lam yahmiloonhaa kamasalil himaari yah milu asfaaraa; bi'sa masalul qawmil lazeena kaazzaboo bi aayaatil laah; wallaahu laa yahdil qawmazzaalimeen (al-Jumuʿah 62:5)
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. (Al-Jumu'ah  : 5)
1 Mufti Taqi Usmani
The example of those who were ordered to bear (the responsibility of acting upon) the Torah, then they did not bear it, is like a donkey that carries a load of books. Evil is the example of those who have rejected Allah’s verses. And Allah does not guide the wrongdoing people.
