Fasting is not obligatory for young children, until they reach the age of adolescence, because the Prophet (peace and blessings of Allaah be upon him) said: “The pens have been lifted from three: from one who has lost his mind until he comes back to his senses, from one who is sleeping until he wakes up, and from a child until he reaches the age of adolescence.” Narrated by Abu Dawood, 4399; classed as saheeh by al-Albaani in Saheeh Abi Dawood.

Nevertheless, children should be told to fast so that they can get used to it, and because the good deeds that they do will be recorded for them.

The age at which parents should start to teach their children to fast is the age at which they are able to fast, which will vary according to each child’s physical makeup. Some scholars have defined this as being ten years of age.

Al-Kharqi said:

When a child is ten years old and is able to fast, he should start to do so.
