Al-Husayn ibn Said, from al-Qasim ibn Muhammad, from Ali ibn Abi Hamzah, from Abu Basir, from Abu Abdillah عليه السلام, peace be upon him: Imam عليه السلام said: “Fasting is upon the boy when he has a wet dream (ihtilam). And fasting and the head-covering (khimar) are upon the girl are when she menstruates, unless she is owned, for there is no head-covering upon her (the bond girl) unless she wishes to cover herself with a head-covering (takhtamir), and fasting is upon her.”
