Day Questions

Studies show that listening to classical music for 30 minutes a day whilst breathing slowly decreases the blood pressure. I need to reduce my blood pressure, so can I start doing this? Will this be a sin?

It is not permissible to listen to the music because of the said reason, unless the high blood pressure was a danger to the health, and its treatment was only by listening to music.

During wudhu, I always become doubtful as to whether I am doing the washing properly e.g. whether or not I am wiping my arms in a manner where it is reaching everywhere, which leads me to be very meticulous in my wudhu. May I ignore this doubt?

If the doubt is conventionally normal, and not a type of waswasah, one should pay attention to it, and therefore wash until he is certain that during the washings the water has reached all parts of the face or arm. If the doubt is a type of waswasah, then one should ignore it.

Seeing that the significance behind the iddah period is so that the father can be identified adequately if the woman becomes pregnant, and contraception almost eliminates the chances of pregnancy, is there any need of the iddah period when using contraception?

The reason behind the waiting period is not necessarily identifying the father if the woman is pregnant. If this was the reason, then it would have been sufficient for Almighty Allah the Divine Legislator to consider one menstrual cycle as a waiting period and not any longer duration. Almighty Allah knows the actual reason behind such legislation. Therefore, the iddah must be observed even if contraception was used.
