Salaah

Q: Can you tell me please in gulf countries I see mostly the Imams finish salaah only with one salam. Is this ok or not?

Q: If we control gas during namaaz, will it be valid or not or again we need to perform the prayer and wudhu? If we are not sure that wind is passed or not at that time, then what should we do?

Q: I want to know that is it permissible to offer Salaah wearing clothes on which deodorant or perfume is used?

Q: Is it compulsory for a female to cover her hands up to the wrists during Salaah i.e. the area of the hands from the fingers till the wrists?

Q: A person is a musafir, visiting a city and shortening his prayers during his visit. May he pray his sunnah prayers sitting on a horse/camel/car whilst in this city (facing any direction) since he is a musafir? Or is this never permissible inside cities?

Q: If I miss fajr and perform it when I wake up before zuhr, then do I perform the two sunnats first or only the fardh?

Q:

1. Should one's heels be apart or touching whilst in sujood? Is this sunnah? If so which part of the foot should be touching each other as a lot of people are not aware of this?

2. If one recites bismillah in the 3rd or 4th rakaat of a fadh salaah after surah fatiha as though he is going to recite a surah, but then realises and doesn't proceed with the surah, would this require sajda-e-sahw?

Q: Should one respond to the Azaan heard over a recording or live streaming?

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)

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.
