[Machine] "It is permissible for the minor to make a will regarding his wealth in the third of his estate or less, and only his guardian can prevent him from doing so for the sake of the fear of poverty upon him. However, at the time of death, he has no right to prevent him."  

الدارمي:٣٣٣١حَدَّثَنَا يَزِيدُ عَنْ هِشَامٍ الدَّسْتُوَائِيِّ عَنْ حَمَّادٍ عَنْ إِبْرَاهِيمَ قَالَ

«يَجُوزُ وَصِيَّةُ الصَّبِيِّ فِي مَالِهِ فِي الثُّلُثِ فَمَا دُونَهُ وَإِنَّمَا يَمْنَعُهُ وَلِيُّهُ ذَلِكَ فِي الصِّحَّةِ رَهْبَةَ الْفَاقَةِ عَلَيْهِ فَأَمَّا عِنْدَ الْمَوْتِ فَلَيْسَ لَهُ أَنْ يَمْنَعَهُ»
