قَالَ يَحْيَى قَالَ مَالِكٌ عَنِ ابْنِ شِهَابٍ، عَنْ سُنَيْنٍ أَبِي جَمِيلَةَ، رَجُلٌ مِنْ بَنِي سُلَيْمٍ أَنَّهُ وَجَدَ مَنْبُوذًا فِي زَمَانِ عُمَرَ بْنِ الْخَطَّابِ قَالَ فَجِئْتُ بِهِ إِلَى عُمَرَ بْنِ الْخَطَّابِ فَقَالَ مَا حَمَلَكَ عَلَى أَخْذِ هَذِهِ النَّسَمَةِ فَقَالَ وَجَدْتُهَا ضَائِعَةً فَأَخَذْتُهَا ‏.‏ فَقَالَ لَهُ عَرِيفُهُ يَا أَمِيرَ الْمُؤْمِنِينَ إِنَّهُ رَجُلٌ صَالِحٌ ‏.‏ فَقَالَ لَهُ عُمَرُ أَكَذَلِكَ قَالَ نَعَمْ ‏.‏ فَقَالَ عُمَرُ بْنُ الْخَطَّابِ اذْهَبْ فَهُوَ حُرٌّ وَلَكَ وَلاَؤُهُ وَعَلَيْنَا نَفَقَتُهُ ‏.‏

Yahya said that Malik related from Ibn Shihab that Sunayn AbiJamila, a man from the Banu Sulaym, found an abandoned child in thetime of Umar ibn al-Khattab. Sunayn took him to Umar ibn al-Khattab.He asked, "What has induced you to take this person?" He answered, "Ifound him lost, so I took him.'' Umar's advisor said to him,' 'Amiral-Muminin! He is a man who does good." Umar inquired of him, "Is itso?" He replied, "Yes." Umar ibn al-Khattab said, "Go, he is free, andyou have his wala' inheritance, and we will provide for him." Yahya said that he heard Malik say, "What is done in our communityabout an abandoned child is that he is free, and his wala' inheritancebelongs to the muslims, and they inherit from him and pay his bloodmoney."
