Quran 62:5 from Surah Al-Jumu'a on Divine Marvels.
مَثَلُ ٱلَّذِينَ حُمِّلُواْ ٱلتَّوۡرَىٰةَ ثُمَّ لَمۡ يَحۡمِلُوهَا كَمَثَلِ ٱلۡحِمَارِ يَحۡمِلُ أَسۡفَارَۢاۚ بِئۡسَ مَثَلُ ٱلۡقَوۡمِ ٱلَّذِينَ كَذَّبُواْ بِـَٔايَٰتِ ٱللَّهِۚ وَٱللَّهُ لَا يَهۡدِي ٱلۡقَوۡمَ ٱلظَّٰلِمِينَ
English translation: (The) likeness (of) those who were entrusted (with) the Taurat then not they bore it (is) like the donkey who carries books Wretched is (the) example (of) the people who deny (the) Signs (of) Allah And Allah (does) not guide the people the wrongdoers
Transliteration: mathalu alladhina hummilu al-tawrata thumma lam yahmiluha kamathali al-himari yahmilu asfaran bi'sa mathalu al-qawmi alladhina kadhabu biayati al-lahi wal-lahu la yahdi al-qawma al-zalimina
