Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
The days are very long in some places making fasting very difficult for children close to the age of puberty. What should they do?
They should not be burdened with more than they can bear. They should be encouraged to fast half the day or most of the day. Although their fast will not be legally valid, they will become accustomed to fasting and their hearts will become attached to it so that when they are older it is easier for them.
How can we make our children love Ramadan?
We do this by mentioning the mercy, bounty and kindness that Allah shows in Ramadan.
