حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، وَعَبْدُ الْعَزِيزِ بْنُ يَحْيَى الْمَعْنَى، - قَالَ أَحْمَدُ - حَدَّثَنَا مُحَمَّدُ بْنُ سَلَمَةَ، عَنِ ابْنِ إِسْحَاقَ، عَنْ دَاوُدَ بْنِ الْحُصَيْنِ، قَالَ كُنْتُ أَقْرَأُ عَلَى أُمِّ سَعْدٍ بِنْتِ الرَّبِيعِ وَكَانَتْ يَتِيمَةً فِي حِجْرِ أَبِي بَكْرٍ فَقَرَأْتُ ‏{‏ وَالَّذِينَ عَقَدَتْ أَيْمَانُكُمْ ‏}‏ فَقَالَتْ لاَ تَقْرَأْ ‏{‏ وَالَّذِينَ عَاقَدَتْ أَيْمَانُكُمْ ‏}‏ وَلَكِنْ ‏{‏ وَالَّذِينَ عَقَدَتْ أَيْمَانُكُمْ ‏}‏ إِنَّمَا نَزَلَتْ فِي أَبِي بَكْرٍ وَابْنِهِ عَبْدِ الرَّحْمَنِ حِينَ أَبَى الإِسْلاَمَ فَحَلَفَ أَبُو بَكْرٍ أَلاَّ يُوَرِّثَهُ فَلَمَّا أَسْلَمَ أَمَرَ اللَّهُ تَعَالَى نَبِيَّهُ عَلَيْهِ السَّلاَمُ أَنْ يُؤْتِيَهُ نَصِيبَهُ ‏.‏ زَادَ عَبْدُ الْعَزِيزِ فَمَا أَسْلَمَ حَتَّى حُمِلَ عَلَى الإِسْلاَمِ بِالسَّيْفِ ‏.‏ قَالَ أَبُو دَاوُدَ مَنْ قَالَ ‏{‏ عَقَدَتْ ‏}‏ جَعَلَهُ حِلْفًا وَمَنْ قَالَ ‏{‏ عَاقَدَتْ ‏}‏ جَعَلَهُ حَالِفًا وَالصَّوَابُ حَدِيثُ طَلْحَةَ ‏{‏ عَاقَدَتْ ‏}‏ ‏.‏

Narrated Dawud b. al-Husain: I used to learn the reading of the Qur'an from Umm Sa'd, daughter of al-Rabi'. She was an orphan in the guardianship of Abu Bakr. I read the Qur'anic verse "To those also to whom your right hand was pledged." She said: Do not read the verse; "To those also to whom your right hand was pledged." This was revealed about Abu Bakr and his son 'Abd al-Rahman when he refused to accept Islam. Abu Bakr took an oath that he would not give him a share from inheritance. When he embraced Islam Allah Most High commanded His Prophet (PBUH) to give him the share. The narrator 'Abd al-Aziz added: He did not accept Islam until he was urged on Islam by sword. Abu Dawud said: He who narrated the word 'aqadat means a pact ; and he who narrated the word 'aaqadat means the party who made a pact. The correct is the tradition of Talhah ('aaqadat).
