باب وُضُوءِ الصِّبْيَانِ
Sahih al-Bukhari 863

Narrated `Abdur Rahman bin `Abis:

A person asked Ibn `Abbas, "Have you ever presented yourself at the (`Id) prayer with Allah's Apostle?" He replied, "Yes." And had it not been for my kinship (position) with the Prophet (ﷺ) it would not have been possible for me to do so (for he was too young). The Prophet (ﷺ) went to the mark near the house of Kathir bin As-Salt and delivered a sermon. He then went towards the women. He advised and reminded them and asked them to give alms. So the woman would bring her hand near her neck and take off her necklace and put it in the garment of Bilal. Then the Prophet (ﷺ) and Bilal came to the house."

حَدَّثَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنَا سُفْيَانُ، حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ عَابِسٍ، سَمِعْتُ ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ لَهُ رَجُلٌ شَهِدْتَ الْخُرُوجَ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ نَعَمْ، وَلَوْلاَ مَكَانِي مِنْهُ مَا شَهِدْتُهُ ـ يَعْنِي مِنْ صِغَرِهِ ـ أَتَى الْعَلَمَ الَّذِي عِنْدَ دَارِ كَثِيرِ بْنِ الصَّلْتِ، ثُمَّ خَطَبَ ثُمَّ أَتَى النِّسَاءَ فَوَعَظَهُنَّ وَذَكَّرَهُنَّ وَأَمَرَهُنَّ أَنْ يَتَصَدَّقْنَ فَجَعَلَتِ الْمَرْأَةُ تُهْوِي بِيَدِهَا إِلَى حَلْقِهَا تُلْقِي فِي ثَوْبِ بِلاَلٍ، ثُمَّ أَتَى هُوَ وَبِلاَلٌ الْبَيْتَ‏.‏
