What is the ruling on creating a website to teach the Persian language to Arabs and English speakers?

There is no harm in establishing a website for teaching the Persian language and others. The basic principle regarding such websites is permissibility. The prohibition of learning or speaking languages other than Arabic is for those who do not have a need for it. However, there is no harm in establishing a website to teach those who need it. If there were any harm, it would be for one who learns and speaks it without a need. Attention must be paid to ensure that the website does not contain any violations of Islamic law, such as images of unveiled women or music.
