Is buying Computer and Technology companies’ stocks Halal or Haram? AND WHY? 
And if Halal, is giving money to mutual fund company that buy these stock (only Technology stocks) Halal or Hram? and Why?


Praise be to Allaah.
 

It is permissible for a person to buy shares in these
companies if they do not deal in riba [usury/interest] (and they do not sell
anything haraam and they do not do business in a manner that is not
Islamic). But if they deal in riba then it is not permitted, because it is
clearly established in the Qur’aan and Sunnah, and by scholarly consensus,
that dealing in riba is haraam.
