Conditions for the validity of Salaah

Q: I would like to know how to find the qibla direction without a compass?

Q: Please advise on the following:

1. When exactly around maghrib time is it not advisable to go outside?

2. Is there anything about not going outside after fajr until after ishraaq or is it okay to walk outside after fajr?

Q:

1.What is the best times for a woman to perform her Salaah? The awwal waqt (when the time enters) or the mustahab time? Please mention the mustahab times for all the five daily Salaah.

2. Can a woman delay Esha Salaah and perform it late?

Q: I have a query about Maghrib Salaah. Up to what time can we perform Maghrib Salaah?

Q: A person made taharri for qibla and read salah, later when the salah time expired, he came to know it was the wrong qibla, does he repeat his salaah?

Q: Kindly explain the satr of a female in detail... does the forehead have to be completely covered and where does the chin end? Some women insist that the burqa must cover the tip of the chin downwards or else salaah is not accepted. Please clarify.

Q: Is it permissible for a hanafi to follow a shafi jamaat for asr salaah if the time for asr hasnt set in for hanafi yet? What is the ruling and other important points to note?

Q: When we go for umrah, all the umrah busses stop for asr prayer according to shafiee time. We (ladies) strictly follow hanafi time. In winters, due to school, we read our zuhur salah after the shafiee asr azan, as hanafi zuhur salaah time is still there. We also read our asr according to hanafi time i.e. late.

So my question is... the bus stops for asr at shafiee time. If we do not get the jamaat, what should we do? Can we read at shafiee time at such circumstances? 

Q: A غير مقلد Islamic teacher said that speaking out the niyyah before praying is bid'ah because it is not proved by sunnah or Sahaabah. Is it right?

Q: Is namaz valid in night suits or T-shirt and trousers for girls?
