Sunnah method of using a miswaak

Q: I would like to know the masnoon way of doing miswaak. Should it be right to left in one go which would be the "length" of the mouth and the "breadth" of the teeth or is it to be done in an up down motion on each tooth starting with the tooth on top on the right which would then be the "length" of the teeth and the "breadth" of the mouth?

Touching an impure object

Q: If there is impurities on an object and I touch it with wet hands. I'm not sure if there was physical signs of it coming onto my hand and I touch a cloth with the same wet hands but you can't see the impurities on this cloth. Did the cloth get impure? If at a later stage my hands are clean and wet and I touch this same cloth but there are no traces/signs of the impurities on my hand, is my hand impure?

Hurmat-e-musaahara

Q:

1. A person feels lust for his wife. He has an erection thinking about her and he accidentally touches his mature daughter's bare hand. Since the lust was for his wife, is his nikaah broken?

2. A person touched his mother with lust. He hasn't confessed and fears that if he does, it will destroy his relationship with his parents. What should he do? He sincerely cries and regrets and repents to Allaah.

3. If after a man touches his daughter with lust and his wife becomes haraam for him and they separate from each other but they still want each other, can they be reunited again in Jannah?

4. Is a man still mahram for his mother whom he had touched with lust where hurmat musaharah has occured? Can he accompany her on a long journey? He regrets sincerely and there is absolutely no temptation and fear of it happening again.

Joining Qur'an khatam groups

Q: Recently few messages have been going around regarding Quran Khatam groups and its authentication, I would like to know if:

1. Is it permissible to join a quran khatam group?

2. Is it permissible to have time limits to complete the khatam?

3. Can you join the group with the intention of making sure that you are completing at least 1 para a week even if the group was created with the intention of esaale sawaab of marhoomeen?

Witr Salaah

Q: My question is regarding witr Salaah. In one Hadith the prophet (Sallallahu Alayhi Wasallam) forbade praying witr like maghrib but in the hanafi fiqh it is prayed like maghrib and I am a bit confused. Please clarify.
