Salaah

Q: Could one do istikhaarah to find out what happened in the past in someone's life such as husband's life before marriage?

Q: A person was in 30% doubt about whether he had wudhu, but gave himself the benefit of the doubt and attended the masjid. He was called to lead the salah as the imam was not present. After salaah this doubt becomes 70% sure that his wudhu had broken previously.

1) What is the condition of his salaah, and all the Muqtadis?

2) if he was 100% sure now that his wudhu had broken, what now would be the ruling?

Q: I understand that one can pray only qadha prayers after fajr and asr, but no nawafil salah. In the case of praying qadha prayers after asr, what time should they stop praying? How many minutes before sunset as this time is haraam to pray?

Q: Does the wrist and ankle of a woman have to be covered in Salaah?

Q: Will I receive the reward of tahaujjd if I perform nafil Salaah after esha before retiring to bed with the intention of tahajjud?

Q: Why do Barelwi Imaams after the Salaam of the Salaah turn towards the North-West for supplication (in the case of India, Pakistan, Bangladesh etc.)?

Q: If there is a animated picture beside me when praying, is it sufficient to place some a shield before it so that it is not visible anymore to me from every angle of my prayer place, or must it be totally packed in?

Q: Can I pray to Allah (in Namaz) with my mini book or paper in my pocket which got napaak with urine or testis, but the books are dry?

Q: Offering Salaah in front of a mirror is correct?

Q: Is it a problem if, while I am performing salaah at home and my husband is also performing some salaah separately, but he stands behind me. Not directly behind me but behind the line I am standing in? Please advise.
