عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ بَاتَ قَتَادَةُ بْنُ النُّعْمَانِ رَضِيَ اللَّهُ عَنْهُ يَقْرَأُ اللَّيْلَ كُلَّهُ قُلْ هُوَ اللَّهُ أَحَدٌ [الإخلاص: 1] فَذَكَرَ ذَلِكَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَالَّذِي نَفْسِي بِيَدِهِ لَتَعْدِلُ نِصْفَ الْقُرْآنِ أَوْ ثُلُثَهُ
Narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that Sayyiduna Qatadah bin Nu'man (may Allah be pleased with him) recited Surah {قُلْ ھُوَ اللّٰہُ اَحَدٌ} throughout the night. When this was mentioned to the Noble Prophet (peace and blessings be upon him), he said: By Him in Whose hand is my soul! This Surah is equal to half or one third of the Holy Qur'an.
