What is the ruling on entering chat websites and getting to know both genders in a spontaneous, innocent way, for the purpose of entertainment and benefit, and using chat terms and abbreviations, and is it permissible for a girl to address a young man with them?

Dating between men and women online is not permissible due to the evils and harms that result from it. A girl addressing a young man or vice versa with phrases that suggest temptation is something that pleases Satan. It is obligatory for a girl to protect herself from situations of temptation and to preserve her time and spend it on what benefits her in her religion and her worldly life. The Messenger of Allah, peace and blessings be upon him, said: "The feet of a servant will not move on the Day of Resurrection from before his Lord until he is asked about five things: about his life - how he spent it; about his youth - how he used it; about his wealth - from where he acquired it and on what he spent it; and what he did with what he knew."
