Question: When does it become obligatory for the child to fast, and what is the age limit?
Response: A child is ordered to pray when he reaches the age of seven, and admonished to do so at the age of ten, and it becomes obligatory upon him when he reaches puberty. And puberty is determined by:
- Excretion of sperm due to [sexual] arousing;
- Appearance of pubic hair around the private parts;
- Having wet dreams, if sperm is excreted;
- Reaching the age of fifteen years.
And similar is the case for a female, in addition to her coming on her menses.
The source for the aforementioned is what Imaam Ahmad and Abu Daawood have related on the authority of the Prophet ﷺ:
Also, ‘Aa.ishah (radhi-yAllaahu ‘anhaa) related on the authority of the Prophet ﷺ:
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet ﷺ and his family and his companions.
