Nafi' said:
وَقَالَ لَنَا سُلَيْمَانُ حَدَّثَنَا حَمَّادٌ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، قَالَ مَا رَدَّ ابْنُ عُمَرَ عَلَى أَحَدٍ وَصِيَّةً. وَكَانَ ابْنُ سِيرِينَ أَحَبَّ الأَشْيَاءِ إِلَيْهِ فِي مَالِ الْيَتِيمِ أَنْ يَجْتَمِعَ إِلَيْهِ نُصَحَاؤُهُ وَأَوْلِيَاؤُهُ فَيَنْظُرُوا الَّذِي هُوَ خَيْرٌ لَهُ. وَكَانَ طَاوُسٌ إِذَا سُئِلَ عَنْ شَىْءٍ مِنْ أَمْرِ الْيَتَامَى قَرَأَ {وَاللَّهُ يَعْلَمُ الْمُفْسِدَ مِنَ الْمُصْلِحِ} . وَقَالَ عَطَاءٌ فِي يَتَامَى الصَّغِيرُ وَالْكَبِيرُ يُنْفِقُ الْوَلِيُّ عَلَى كُلِّ إِنْسَانٍ بِقَدْرِهِ مِنْ حِصَّتِهِ.
"Ibn 'Umar never refused to be appointed as guardian." The most beloved thing to Ibn Sirin concerning an orphan's wealth was that the orphan's advisor and guardians would assemble to decide what is best for him. When Tawus was asked about something concerning an orphan's affairs, he would recite: '...And Allah knows him who means mischief from him who means good...' (V 2:220). 'Ata said concerning some orphans, "The guardian is to provide for the young and the old orphans according to their needs from their shares."
