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?.

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?
