Jamaat Salaah and Imaamat

Q: What is the ruling regarding qiyaamul lail / shabeena which is read in jamaat after the taraweeh salaah as is taking place in certain masaajid in durban?

Q: Is it permissible in Islam to have a tattoo on one's body? I performed salaah behind a person who has a tattoo on his skin. Is the salaah valid?

Q: What's the status of the Salaah of the Imaam and the muqtadees if the Imaam is known to be a follower of a certain mazhab eg: Shafi, but when he goes on the musallah he performs namaaz like a Hanafi, when questioned why he does that his simple answer was "I don't want to confuse the people". What is the status of the muqtadis and Imaams Salaah?

Q: Is it permissible to read Salaat-ut-Tasbeeh in Jamaat.

Q: What is the ruling with regards to women attending the musjid? Are there any Ahaadith that state that we should not stop women from attending the musjid?

Q: Is it permissible for a person to stand alone in a saff in Jamaat salaah? If not, then what should the person do in this situation?

Q: Are ladies permitted to stand in the saffs of the men in jamaat salaah. In Bahisti Zewar under the section "Prerequisites of Salaah" there is a masalah that says that the Imaam must make niyyat for a woman who intends joining the Jamaat Salaah if she is standing in line with the men. However if she is standing behind them, then the Imaam does not have to make niyyat for her. This masalah seems to show permissibility for the women to be in line with the men?

Q: Is it permissible to follow an Imaam whose trousers is below his ankles and will the Salaah be valid?

Q: If a man is performing salaah and a woman comes and stands next to him, but she is not in salaah, she is merely standing next to him, does this invalidate the salaah? Is the ruling same for individual salaah as well as jamaat salaah? Furthermore, is there a difference in the masala if the woman is a disbeliever?

Q: Is there any Hadith about joining the masbooq in Jamat?
