What is the ruling on thighing with young girls and one's fiancée in Islam?

Islam is the religion of Allah, which He chose for humanity. Allah perfected the religion, completed His favor, and approved Islam. Therefore, it is not permissible for a Muslim to accept the accusations of the disbelievers against it. As for mufakhadha (thighing), it refers to enjoying between the thighs, and it is permissible with a contractually married wife as long as it does not harm her, but it is forbidden with anyone else.
