Using medications and supplements

Q: I have a question regarding physical relations between husband and wife. My friend is very religious and her husband is moderately religious. She has a question that if her husband uses any medication or pill like ecstasy for good relations then is that allowed in Islam. He is adamant that men use different herbal and all type of medicines for enjoyment and women should also be allowed. Kindly guide us with your knowledge with reference.

Replying to the Azaan

Q: Should we reply to the adhaan by repeating its words and also saying the dua after adhan when it is heard in this three different scenarios:

1. On the radio (even if it is from another country such as Saudi Arabia)

2. From the masjid (loudspeakers)

3. From the masjid (no loudspeakers)

Doubts with regards to qiraat

Q: I suffer from OCD and during namaz I forget if I have read somthing, so I will start the namaaz over again or I will repeat what I think I forgot. Also sometimes I think I said somthing wrong and I will repeat that part until I think I said it right. It is so stressful for me to read namaz and doing this takes so much time. A simple asr namaaz that takes anyone else 5 maybe 10 minutes takes me around 20-30 minutes to read. This takes up so much time during the day I can never finish anything else. I need to know if I think I have forgotten somthing or said somthing incorrect what should I do because it is obviously not normal to take so long to pray even the simplest of namaz. I just can never tell what really happend and what is my doubts.
