[1/100] al-Khisal: From his father from Sa’d b. Abdallah from Ahmad b. Muhammad b. Isa from Ahmad b. Muhammad b. Abi Nasr al-Bazanti from Abi al-Hasan – the servant and seller of pearls – from Abdallah b. Sinan from Abi Abdillah عليه السلام, he (Abdallah b. Sinan) said: my father asked him about the orphan while I was present – when does his affair become permissible [when does the authority to oversee his affair devolve to him]? he said: when he attains his maturity, he said: what is his maturity? he said: beginning to have nocturnal emissions, he said: a boy may be eighteen years or a little below that or a little more than that and yet does not have nocturnal emissions (what then)? he said: if he becomes pubescent and something begins to be written for him (of good-deeds and sins by the angels) – then his affair [taking charge of financial decisions] is valid unless he is a fool or mentally incapacitated.
