Jamaat Salaah and Imaamat

Q: Can a waladuz zina (illegitimate child) make imamat for taraweeh salaah in Ramadhaan?

Q: I want to know something about drugs. I will be leading taraweeh for the first time this year. Unfortunately, I am in the grasp of drugs. Is it true that if I take them within 40 days of Ramadhaan, the taraweeh I lead will not count?

Also, does this apply to drugs other than marijuana, like molly, cocaine, and lsd?

Please take into account that I am trying to stop, but slowly as the withdrawal effect is immensely strong.

Q: When praying behind the imam in Zuhr and Asr prayer, should we recite Surah Fatiha and a Surah in the first 2 rakaats and only Surah Fatiha in the last rakaat.

In Fajr, Maghrib and Esha, I know we should keep quiet and listen but in the last 2 rakaats when the imam is silent, should we recite Surah Fatiha only?

Q: During the Friday prayer, the imam paused two times during the recitation of Surah Faatihah, and once during the recitation of another surah. The pause was longer than the time it takes to say 3 times سبحان الله , and it seemed that the imam was weeping. Will the Friday prayer be valid?

Q: Without completing tashahhud behind the imaam in the second and fourth rakaah, is my salaah valid?

Q:

1. If I missed the prayer with jamat, can I pray with my family members (wife, sons, daughter) at home?

2. Can I miss the congregation prayer at the masjid and pray in congregation at home because the imam of the masjid makes masah on normal socks?

3. If I am sure that I will miss the jamat, is it compulsory to go to the masjid and pray alone or second jamat?

4. I hear the azan and iqamat and complete namaz but I am very tired to go and pray in the masjid, can I pray at home later with my family?

5. For Asar prayer, instead of praying with jamat in a Hambali maslak time, can I delay the prayer and pray (alone or with my family) at home after the Hanafi maslak time begins. (I listen to the complete azan and iqamat and jamat from the masjid's speakers).

Q:

1. How many saffs (rows) can we cross while in the state of namaaz in order to fill the front saffs (rows)?

2. How much can we move horizontally in the same saff (row) in order to fill the gap?

Q: If a person arrives late for salaah and notices that the saff of the children is going to join up with the sufoof of the adults, should he move the children to the back? 

Q: When I offer namaaz in the masjid, when going into sajdah, many peoples heads touch the feet of the person in the front row. Whats the ruling on it?Does it affect the namaaz in any way?

Q: If one is physically able to make it to the musjid but has a contagious disease (flu, measles etc.) must he attend?
