Sunan an-Nasa'i, Book 27, Hadith 107 (In-Book) ⓘ

It was narrated from 'Abdul-Hamid bin Salamah Al-Ansari, from his father, from his grandfather, that he became Muslim but his wife refused to become Muslim. A young son of theirs, who had not yet reached puberty, came, and the Prophet seated the father on one side and the mother on the other side, and he gave him the choice. He said: "O Allah, guide him," and (the child) went to his father.

أَخْبَرَنَا مَحْمُودُ بْنُ غَيْلاَنَ، قَالَ حَدَّثَنَا عَبْدُ الرَّزَّاقِ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عُثْمَانَ الْبَتِّيِّ، عَنْ عَبْدِ الْحَمِيدِ بْنِ سَلَمَةَ الأَنْصَارِيِّ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، أَنَّهُ أَسْلَمَ وَأَبَتِ امْرَأَتُهُ أَنْ تُسْلِمَ فَجَاءَ ابْنٌ لَهُمَا صَغِيرٌ لَمْ يَبْلُغِ الْحُلُمَ فَأَجْلَسَ النَّبِيُّ صلى الله عليه وسلم الأَبَ هَا هُنَا وَالأُمَّ هَا هُنَا ثُمَّ خَيَّرَهُ فَقَالَ ‏ "‏ اللَّهُمَّ اهْدِهِ ‏" ‏ ‏.‏ فَذَهَبَ إِلَى أَبِيهِ ‏.‏
