The most important reasons are the following:

- For Shiites: if the mother’s religion is different.

- For Sunnis: the mother’s custody is extinct when the child reaches the age of 5 if the mother’s religion is different.

- For Sunnis and Druze if she remarries someone who is not the child’s “mahram”. As for the Shiites, she loses the right to custody whether she remarries the child’s mahram or marries a non mahram.

For all three communities, a mother can redeem her right to custody if the reason underlying its extinguishment elapses.
