Humayd ibn Ziyad has narrated from al-Hassan ibn Muhammad ibn Sama‘ah from ‘Abd Allah ibn Jabalah from abu al-Mighra’ from abu Basir who has narrated the following: “Abu ‘Abd Allah , has said, ‘When a boy becomes ten years old and makes a will about one-third of his assets for a right cause, his will is permissible; but when he is seven years old his will about only a small amount of assets is permissible.’”
