Dealing in Shares

As salaamu alaikum – Muftisabk my daughter(Yusra) is starting studies at the university please make Dua for her kamiyabi.

I run a tyre sales business, it is becoming cumbersome and tiring which is effecting my health as well. I am expecting some additional income with which I would like to start doing trading in shares online form my home and to slowly slow down on the tyre business. As it will give most importantly to get connected with the Masjid to do Deeni work and also give me enough time to spend with the family and extended family.

Please guide me as to what type of shares are permissible to deal in and what caution should I take in doing this business.
