What is the ruling on buying and selling shares? Please note that some scholars regard shares from all companies as haraam. We hope that you can explain.

I am an engineer working for a company. One of the perks that I get in return for my work is a sum of money to compensate me for what I have spent on updating my engineering skills, such as conferences and books. If I do not use the money during one year, the company keeps the money. The company also allows me, as a one-off, to buy a computer without stipulating any maximum limit on the price of this computer. Some of my colleagues who have the same perks bought a computer and gave the invoice to the company to show that they bought this computer, then they returned the computer to the store and took the money and kept it. Is it permissible for me to do the same thing?.

Is it valid to read Qur’aan from the computer instead of from the Mushaf ?
In other words, reading from websites on the Internet or from text files that contain the entire Qur’aan, which is displayed on the computer screen. I work in a company and during my breaks I read Qur’aan on the computer.
Is it necessary to have wudoo’ for this kind of reading, as is the case when reading from the Mushaf?.

Is it permissible to pray in a mosque where the ground floor is controlled by the Shi‘ah and the Sunnis control the upper floor?

I have a few questions concerning parents:
1. What right does my Mother have over me? 
2. What right do I have over my mother? 
3. What do I have the freedom to do (which is Halal or Mubah, Ofcourse) without my Mother having the right to stop me? 
4. When does the Father have the final say in a matter? 

I love my mother very very very much. She is very over protective, and sometimes I feel like I'm in chains. I know she is doing it out of extreme love for me. How can I tell her that I need a little choice of my own in life.

Some scholars of tajweed said that it is obligatory to read Qur'aan with the rules of tajweed. Is that true?

Is it mustahabb to say Qunoot during the daily prayers for our brothers in Gaza, so that Allaah will relieve them of the aggression of the Jews? In which prayer should Qunoot be said?

I am one of those who send blessings upon the Prophet between 50 and 100 times a day, according to circumstances. I say: “Allahumma salli ‘ala Muhammadin wa aali Muhammad (O Allah, send blessings upon Muhammad and the family of Muhammad).” There are some people who tell me that my sending blessings upon the Messenger of Allah is lacking. Can you tell us – may Allah reward you with good – what is the ideal way to send blessings upon the master of mankind, and is the way I am doing it really lacking?

I have committed many sins which no one knows of except Allaah. What do I have to do so that Allaah will accept my repentance?
