عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو رَضِيَ اللَّهُ عَنْهُمَا أَنَّ أَبَا أَيُّوبَ رَضِيَ اللَّهُ عَنْهُ كَانَ فِي مَجْلِسٍ وَهُوَ يَقُولُ أَلَا يَسْتَطِيعُ أَحَدُكُمْ أَنْ يَقُومَ بِثُلُثِ الْقُرْآنِ كُلَّ لَيْلَةٍ قَالُوا وَهَلْ يَسْتَطِيعُ ذَلِكَ قَالَ فَإِنَّ قُلْ هُوَ اللَّهُ أَحَدٌ [الإخلاص: 1] ثُلُثُ الْقُرْآنِ فَجَاءَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَهُوَ يَسْمَعُ أَبَا أَيُّوبَ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ صَدَقَ أَبُو أَيُّوبَ
It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that Sayyiduna Abu Ayyub (may Allah be pleased with him) was in a gathering, and he said: Is there anyone among you who is unable to stand in prayer at night with one third of the Qur’an? They said: Is it possible for anyone to have such strength? He said: Surah Al-Ikhlas is one third of the Qur’an. In the meantime, the Noble Prophet (peace and blessings be upon him) arrived, and after hearing Abu Ayyub, he (peace and blessings be upon him) said: Abu Ayyub has spoken the truth.
