Is it permissible to lie down with one's mother in the same bed at night after reaching the age of nineteen?

It is not permissible for male children, once they reach puberty or the age of ten, to sleep with their mothers or sisters in the same bed. This is based on the Prophet's (peace be upon him) saying: "Command your children to pray when they are seven years old, and beat them for it when they are ten years old, and separate them in their beds." This is a precaution for souls, to distance them from inciting temptation, and to block the means to evil. This separation includes all children, males and females, whether with males or females. As for those under ten years old, it is permissible for them to sleep with their mother or sister in her bed due to their need for care and the absence of temptation. However, if they are adults, they may sleep in the same place if each of them has their own bed.
