Conditions for the validity of Salaah

Q: When determining qiblah direction, would a Google earth search be considered a valid qiblah direction?

Q: A person entered the musjid while the congregational salaah had started and he had not performed Tahiyyatul Musjid. Can he join the congregational salaah and intend (i.e. if it was Maghrib time) that he is performing 3 rakaats of the fardh salaah of Maghrib and he is also performing Tahiyyatul Musjid?

Q: I normally refer to the sunrise timing from the salah timings in Dubai which I Google. However sometimes there are differences of sunrise timings when compared with calendars. Some say 6:19, some state 6:17, some say 6:15.

So if I finished my Fajr Salah at 6:17am, which exact time should I use. I get confused which table should I refer to.

Q: Is a woman allowed to perform salaah with her niqaab covering her face in the presence of non-mahram men?

Q:

1. I now wear 2 khimars, 2 shalwars, 1 half-sleeve T-shirt underneath two kurtas, and a pair of gloves (and I try my best to tuck in the sleeves of the 2 kurtas into them) until the wrists because my clothes are thin and quite see-through. After wearing these clothes, I feel comfortable, Alhamdulillah, that the satr is not going to be seen.

My question now is that if a woman goes into sajdah and if she is wearing a see-through kurta (and no other shirt) and even though her khimar (which reaches almost until her knee cap when she is standing) still covers her body during sajdah by draping around it but does not cover the kurta itself such that if someone (like an angel or a jinn) were to watch her from below the ground, they would see the kurta uncovered by the khimar but someone standing on the ground could not see anything underneath the khimar at all. Does this invalidate the prayer?

2. If two limbs are exposed during Salaah, each less than a quarter of its whole area, how can a woman know if it invalidated her prayer? What is the length she can measure to?

3. If a woman wears shalwar (which kind of shows her figure but is not figure-hugging like tights), then is her Namaz valid?

Q: Can you please explain in detail what the makrooh times are for salaah, sajdah tilawat, nafl salaah, qada salaah, and tahiyyatul wudhu? I read it in a book, and I’m confused. Like, for example, after asr Athan but BEFORE praying, you can do sajdah tilawat, and AFTER praying Asr but BEFORE Maghrb, you can pray qada salaah.

Q: Will a woman be allowed to wear a long dress or long skirt to read salaah?

Q: Can I pray in leggings if my top ends a few inches above my ankles?

Q: Until what time can you read your zuhr salaah?

Q: Is not covering the feet below the ankles for woman against sunnah? I have severe waswasa and I found out that except for Hanafi's, others consider the feet as awrah. Are my prayers invalid as I didn't cover it after knowing about the ruling. Why do Hanafi's not consider the feet as awrah. I feel scared that my namaz isn't valid. What should I do?
