nasai-kubra:10467 – Qutaybah b. Saʿīd > Mālik > ʿAbd al-Raḥman b. ʿAbdullāh b. ʿAbd al-Raḥman b. Abū Ṣaʿṣaʿah from his father > Abū Saʿīd al-Khudrī > a man

[Machine] A man heard someone reciting {Say, "He is Allah, [who is] One} [Al-Ikhlas 1] repeatedly. When morning came, he went to the Prophet Muhammad ﷺ and mentioned it to him. The Messenger of Allah ﷺ said, "By the One in whose hand is my soul, it is equivalent to one-third of the Quran." Isma'il ibn Ja'far contradicted him. 10468 Abbas ibn Abdul Azim informed us: Muhammad ibn Jahdam told us: Isma'il ibn Ja'far told us from Malik, who mentioned a word with its meaning from Abdul Rahman ibn Abdullah ibn Abdul Rahman ibn Abi Sa'sa'a.  

الكبرى للنسائي:١٠٤٦٧ – أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ عَنْ مَالِكٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَبْدِ اللهِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبِي صَعْصَعَةَ عَنْ أَبِيهِ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ أَنَّ رَجُلًا

سَمِعَ رَجُلًا يَقْرَأُ {قُلْ هُوَ اللهُ أَحَدٌ} [الإخلاص 1] يُرَدِّدُهَا فَلَمَّا أَصْبَحَ جَاءَ إِلَى النَّبِيِّ ﷺ فَذَكَرَ ذَلِكَ لَهُ فَقَالَ رَسُولُ اللهِ ﷺ «وَالَّذِي نَفْسِي بِيَدِهِ إِنَّهَا لَتَعْدِلُ ثُلُثَ الْقُرْآنِ» خَالَفَهُ إِسْمَاعِيلُ بْنُ جَعْفَرٍ 10468 أَخْبَرَنَا الْعَبَّاسُ بْنُ عَبْدِ الْعَظِيمِ قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ جَهْضَمٍ قَالَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ عَنْ مَالِكٍ وَذَكَرَ كَلِمَةً مَعْنَاهَا عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَبْدِ اللهِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبِي صَعْصَعَةَ

bukhari:7374 – Ismāʿīl > Mālik > ʿAbd al-Raḥman b. ʿAbdullāh b. ʿAbd al-Raḥman b. Abū Ṣaʿṣaʿah from his father > Abū Saʿīd al-Khudrī > a man

A man heard another man reciting (in the prayers): 'Say (O Muhammad): "He is Allah, the One." (112.1) And he recited it repeatedly. When it was morning, he went to the Prophet ﷺ and informed him about that as if he considered that the recitation of that Sura by itself was not enough. Messenger of Allah ﷺ said, "By Him in Whose Hand my life is, it is equal to one-third of the Qur'an."
