Salaah

Q: Do we need to recite surahs in order as per the Quran Majeed?

If a person doesn't know this ruling before and afterwards he comes to know it, he recites in order, what is the ruling on this?

Q: We travelled from India on 4th Aug 4pm and reached our hotel in Makkah on 5th 00:30. We calculated our stay as 14 days (5 to 18) and we had intention that on 18th night or 19th morning we will leave for Mina. We left for Mina 19th morning 03:00am. We came back to Makkah on 23rd evening and stayed till 4th Sep. We offered qasar all in Makkah and during haj and then after coming from Haj as our stay at Makkah was not 15 days before leaving Mina and even after coming back from Haj it was not 15 days. Is it correct?

Few people calculate Mina, Arafat, Muzdalifa stay as in Makkah only, so as per them it is 30 days in Makkah and we should offer full salah. Is it correct?

Q: In some coutries, ulama say that zikr (like Lailaha illahu wahdehu la shareeka lehu... zal jadda minkal jadd) which is done after prayers with loud voice is sunnah. We have never heard our ulama or Imamas in Pakistan doing zikr after prayers with audible voice. Can you please guide what is Sunnah?

Q: One of my cousins and her friends are planning to go on a holiday, which requires 1.5 hours to 3 hours flight journey and staying there for 7 days in a friend's known family guest house.

My question is, can they travel without a mahram? They are taking the fact that a woman can travel from one safe place to another.

Q: If any Imam chews tobacco (zarda plan), is my salat complete behind that Imam?

Q: I made the intention in my heart to recite long surahs in fajr salaah, but I forgot and recited short surahs instead. Does this make sejdah sahw waajib?

Q:

1. Can one read multiple duas that come from the hadith after tashahud and before tasleem?

2. Can one read one dua multiple times after tashahud and before tasleem like: Bismillahi ala dini wa nafsi wa waladi wa ahli wa mali Or Allah humu ini aoothbika minal mathami wal magram?

Q: I would like to know if I read Fajr Salaah and after I finished, I saw the time was 5:39. Few seconds later, when I checked the time again It was 5:40 and sunrise is at 5:40. Should I repeat the salaah or is it okay and within the time?

Q: While lying in bed I am sometimes unable to face the Qibla as I need assistance and it is difficult for my wife to do it alone. Should I still raise my head or can I read salaah lying flat down (by raising my head I will not be face to Qibla still)?

Q: I was confused when exactly should one say "Rabbanna wa lakal hamd". Is it when you rise from bowing immediately or after you put your hands down and stand for a short while before going down?
