Salaah

Missing salaah due to shopping

Q: If a woman is out with her family to a hotel to eat and went to a mall to enjoy some time... So what must she  do if salah time is due? She prayed asr at home and went outand now it's maghrib time and she can't pray because there is no women's prayer room in the malls or hotels... So what must she do in this situation?

If she does jama' salah in her home, like praying 4 rakah of asr and then 3 rakah of maghrib in the same time because she won't get a place to pray maghrib, is this correct?

Surahs and du'aas in salaah with illustrations of the postures printed on a musalla for non-Muslims to perform salaah on

Q: Can these musallas be used for new Muslims so they can read the correct du'aas and surahs in salaah? 

It's basically a 1.5 metre piece of leather/strong plastic, and printed on it are; Surah Faatiha and two other surahs plus all the du'aas in salaah with an illustration of the posture they're to be recited in. 

The idea is for the new Muslim to pray their salaah on this mat, reading from it and following the illustrations as they pray their salaah. This mat goes directly on the ground and the person is standing on it.

Imaam making a mistake in qiraat and remaining silent for more than three subhanallahs

Q: The imaan was reading Surah Sajdah. He got stuck repeatedly and paused for more then 3 subhanAllahs. Does salaah need to be repeated because he didn't make sijdah sahw? 

He got stuck like this before. He seems to be ignorant of the masla. 

He also stands with his legs far apart like a ghair muqalid. What should be done in this situation? How should he be corrected?

Missing Fajr Salaah

Q: I had a wet dream and went for ghusl. There was like 18 mins left for sunrise to pray Fajr when I went to do ghusl. While doing ghusl, when I checked my phone it was 7:16 and time for sunrise was going to be over at 7:25. So when I saw the time was 7:16, I did fast and made a call to a person which took 15 seconds. Then I started washing my parts but unintentionally it took more time. When I finished washing my parts it was 7:24 and now the time was over because I had to make wudu also. I made wudu and prayed my salah. Is my salah valid?
