Islamic schools taking Thursdays

Q 2: Is it permissible for a Muslim to open schools on Thursdays and Fridays?

A: Yes it is, as long as this does not result in anyone missing an obligation, or doing a prohibited action, but it is impermissible to sit for studying on Fridays before the Prayer time, either at school or in the Masjid (mosque), for the prohibition of doing this is authentically reported. However, it is permissible to make both days or either of them holidays, due to what is previously mentioned in the answer of the first question.
