Salaah

Q: Should we read a dua when the imam reads the last verses of Surah Gashiyah?

Q: I want to go on holiday abroad. I am a 48 year old female. After I asked, I cannot get a mahram to go on holiday with me. Can I go alone since I heard that after 50 years old then no mahram is required?

Q: With regards to Taraaweeh:

1. An Aayah was recited correctly. The Imaam thereafter repeated the Aayah and changed it (incorrectly) due to some doubt. Is the initial correct recitation or the second recitation which was incorrect taken into consideration? Does the Aayah have to be repeated?

2. For the purpose of listening to the Luqmah of a Saami', the Imaam remained silent for the duration of 3 Subhaanallaah or more (he did not recite Qiraat for that duration). Should Sajdat-us-Sahw be made?

3. Additionally, if a person because of some disturbance missed an Aayah in Surah Faatihah, or one sentence in his At-Tahiyyat, does he have to make Sajdatut-us-Sahw? To what extent is the Surah Faatihah and At-Tahiyyat Waajib? 

Q: If a person forgets to recite surah faatihah or leaves out any other waajib in a sunnat salaah and only remembers after the time has passed, does he need to repeat the salaah or not?

Q: I don't have a right hand index finger the one we raise in Salaah. Does this mean anything in Islam?

Q: Can we read "rabbana hablana min azwajina.....imama" and "rabana aatina fidduniya hasanah......waqina azab-al-meezan" in namaz after durood and before salam?

Q: What if a person makes a mistake in the first salam of salah (i.e changes ح to خ) and without correcting it moves to the second salam, is the prayer valid?

Q: What is the manner of offering khusoof prayer?

Q: How to pray missed namaz in the next namaz time, do we first pray the present namaz or the missed namaz?
