"The main purpose of the conversation should be marriage through legal ways, and it shouldn't have any other goals that could mark a violation of Sharia law. Any personal details, which could arouse lust, must not be addressed during the conversation," the council said.
The Ma'an news agency said the council also ruled women must avoid describing their physical appearance, refrain from displaying photos and be accompanied by a family member if meeting an online connection in person.
The council cautioned women to refrain from using "sentimental and tender" tones when communicating with men online and ordered parents to monitor their children's online activities.
