2- أَحْمَدُ بْنُ مُحَمَّدِ بْنِ عِيسَى [عَنْ مُحَمَّدِ بْنِ عِيسَى] عَنْ مَنْصُورٍ عَنْ هِشَامٍ عَنْ أَبِي عَبْدِ اللهِ قَالَ انْقِطَاعُ يُتْمِ الْيَتِيمِ بِالاحْتِلامِ وَهُوَ أَشُدُّهُ وَإِنِ احْتَلَمَ وَلَمْ يُؤْنَسْ مِنْهُ رُشْدٌ وَكَانَ سَفِيهاً أَوْ ضَعِيفاً فَلْيُمْسِكْ عَنْهُ وَلِيُّهُ مَالَهُ.
2. Ahmad ibn Muhammad ibn ‘Isa has narrated from [Muhammad ibn ‘Isa] from Mansur from Hisham who has narrated the following: “Abu ‘Abd Allah , has said, ‘The orphan-hood of an orphan is over when he experiences wet-dream, and that is the time when he reaches manhood but if he experiences wet- dream and does not have proper understanding because of dimwittedness or weakness, then his guardian must keep his assets for him.’”
