Jamaat Salaah and Imaamat

Q: If an imam performed Salaah in a time and he is in janaabat and he knows that he is in janaabat but still he became Imam and performed the Salaah, and he did this many times like more than 100 times and for different prayers, so now if he wants to make tauba but he still can't tell those people that repeat their Salaah because actually he also don't have any count of prayers so if he did tauba is there any possibility that Allah Ta'ala will forgive him?

Q: Who should lead the salaah? A hafiz of the quran who has a nice voice, but who trims his beard under the required length and who's robes flows under his ankles, or someone who isn't hafiz but is righteous adheres to the Sunnah? If the first leads the salaah should one repeat the salaah?

Q: In todays measurements of kilometers, what is the minimum distance a person has to be from the musjid for salaah to become fard on him in the musjid. In other words, when will it be permissible for him to perform salah at home.

Q: I just want to ask, in our place I am the only one who follows the way of Imaam Abu hanifa on how he prays and the rest they pray like Imaam Shafi'ee, is that ok?

Q: In Mecca, inside Safwa Towers there is a very large prayer area (with its own sound system, recitation coming direct from the Haramain Sharifain Imam). Does this area come under the precinct of the Haramain? In other words, do I get the same reward as praying inside the Haramain Sharifain as praying in the Safwa Towers’ prayer area?

Q: I live just more than 4.9 km from the nearest Masjid. Am I sinful in not attending the Masjid for Salaah?

Q: During Ramdhaan in the Haramain both at Makkah and Madinah they conduct Tahajjud namaaz in Jamaath during the last 10 days from 1 am to 2.30 am. Following this now a days the same method is being followed in mosques in our country (India) as well and also women participate in this congregation but of course in a enclosure segregated for women. Also now a days women attend Jummah namaaz in mosques on a regular basis. Please give your expert option on these two issues.

Q: Can I make imaamat if I am a mazoor with the disease of urinary incontinence?

Q: Can a person sitting on the floor lead the salaah with jamaat? What about if sitting on a chair?

Q: A person is on a plane with his wife, and the time for salaah sets in. There are no other Muslims visible that would be able to perform salaah with the man in jamaat. In this case 1) Would it be better that the husband and wife perform salaah with jamaat or better individually? 2) If there is minimal space and the wife would have to stand almost next to the husband in salaah with jamaat, perhaps on the left hand side, would it be permissible to perform the congregational salaah in this manner?
