Hadith on Quran: Can you read a third of Quran in one night?

Abu Sa’id al-Khudri reported: The Prophet, peace and blessings be upon him, said to his companions, “Is it difficult for one of you to recite a third of the Quran in a single night?” That was difficult for them, so they said, “Which one of us can do that, O Messenger of Allah?” The Prophet said, “The chapter, ‘Allah, the One, the Refuge’ (112:1) is worth one-third of the Quran.

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِأَصْحَابِهِ أَيَعْجِزُ أَحَدُكُمْ أَنْ يَقْرَأَ ثُلُثَ الْقُرْآنِ فِي لَيْلَةٍ فَشَقَّ ذَلِكَ عَلَيْهِمْ وَقَالُوا أَيُّنَا يُطِيقُ ذَلِكَ يَا رَسُولَ اللَّهِ فَقَالَ اللَّهُ الْوَاحِدُ الصَّمَدُ ثُلُثُ الْقُرْآنِ
