Jamaat Salaah and Imaamat

Q: If I prayed along with the imam and when he got up from ruku I got up along with him, I did not wait till he got up fully. Is my prayer valid? 

Q: I have a question regarding joining the jamaat for salah late. What is the ruling regarding the situation if I join the jamaat while it was in qiyam. And soon after my joing the jamaat (after 2-3 secs) the Imam goes into ruku. I didn't get enough time to recite surah fatiha. Will I get that rakat as I couldn't recite the Fatiha or I need to repeat it by myself after tasleem of Imam?

Q: One day I was leading three people in asr prayer. In my second last rakaat I felt like something was coming from my private part. I continued with the prayer. After I finished I went to the toilet and I found it was mazi. I came back after I purified myself and I did my ablution but the people we prayed together were gone. I performed the prayer alone again. So what can I do about them?

Q: Is my prayer valid behind an Imam

1. Who was wearing normal thin socks and I saw him doing masah on them during wudhu.

2. Who was wearing normal thin socks and I did not saw him doing masah on them.

Please note that majority of the people do masah on normal Socks here.

Q: If I miss one or two rakats of jamaat salaah, will I get the reward of jamaat salaah? Till what stage of salaah if one joins will he get the reward of jamaat? 

Q: If ladies are following the imam in a separate area from the men, does the imam still have to make niyyat for their imamat for their salah to be valid? Behishti zewar suggests that even if the imam doesn't make niyyat, their salah will be correct, in the situation where they won't be coming next to the men.

Q: I have a few questions regarding a late comer joining salaah:

1.Is it important to recite sana once you standup to complete your prayer?

2. What if sana was recited when the person joined in the 2nd, 3rd or 4th rakaat

3. Due to misunderstanding and following someone, if a person follows a different procedure to complete the missed rakaats in salaah for a couple of years and now he comes to know correct Hanafi procedure, will his passed salaahs be valid?

4. Is the below procedure correct as per Hanafi mazhab: If a person joins jamaat salaah and says salaam at the end of the 2nd rakaat and after salam he stands up and doesnt read sana and treats this rakat as the 4th rakaat. He only recites surah fatiha and completes his salah. Is his salaah valid or does he have to stand up recite sana, surah fatiha and a surah to complete his salah?

Q: If any Imam chews tobacco (zarda plan), is my salat complete behind that Imam?

Q: If a husband and wife want to read salaah side by side and seperately (not in congregation), can they do so? I read salaah beside my husband several times and seperately (he wasn't leading me in jamaat). Are the salaah valid or should I repeat them? If I am reading salaah with my husband and he is leading me in congregation, then where should I stand? 

Q: If I joined the maghrib salaah in the last rakaat or while the imaam was reciting tashahhud of the second rakaat, then how should I perform the two rakaats that I missed, and when should I recite the thana?
