Q 4:
I usually fast on Monday, Thursday, and Friday of each week, is there anything wrong with this?
A:
If the reality is as you mentioned, it is good as long as you do not single out Friday with Sawm (fasting), because of the Prophet's saying:
None of you should fast on Friday (Part No. 10; Page No. 348) unless he fasts a day before or after it.
