Salaah

Q: I know there is more reward for Salaah prayed in congregation for men, please provide me with Hadith to support this fact.

Q: I am Islamically 14 and not sure if I am baaligh. I have released mazi and probably wadhi but not mani. Am I baaligh and can I perform Salaah as an Imaam?

Q: I got two questions;

1. Do we need to recite anything while praying behind an Imam? Is it compulsory to read a surah?

2 When we reciting fathiha or a surah in a prayer, what if we do a mistake and we realize it at the moment, what shall we do? Example 01- When we reciting surah al naas and after recitng half we random come up with another verse of another surah like surah al quraysh. Example 02, when we reciting surah al nas half and what if we cant remember the other half ? Can we skip the surah?

Q: When the Imaam ends the qiraat before going to ruku, some people drop their hands before the Imaam says the takbir. What is the Shar'ee ruling regarding this? Is it permissible for them to drop their hands?

Q: When you perform salaah, when doing takbeer to start, should we look up or down? And after raising from rukuand saying "samirallahhulimanhamida", some says you have to say "allahumma rabbanawakalhamd" and others only "rabbana lakalhamd"? Which one is correct according to sunnah? And is it obligatory to say it? If i did not say it, are all my prayers invalid?

Q: I have many qaza namaz remaining. I want to offer a nafil namaz on Friday for 7 weeks for sharh e sadr. Can I do this or first I have to offer qaza salats?

Q: If Salatul Esha is missed by someone, then how many rakaats of salaah should be offered?

Q: This weekend I was out musafir for a few days with a few friends. We came to a masjid to perform salaah. Two friends we finished making wuduh and the third was still making wuduh so the two of us decided to start our farad thinking the 3rd brother will join us. Our first rakat was almost finished when the third brother finished his wudu. The brother didn't join us but performed his salah on his own. When asked why he didn't join us he said because we didn't wait for him. Is this brother sinful for doing that?

Q: We had a tashkeel of 17 days in Karachi. When we reached the railway station for Lahore we offered four rakaats of asr before the train left from the station. Is it done or we should perform two rakaats?

Q: If one just built up a lot of sweat after playing sports and it's time for Salaah, can he perform his Salaah with all that perspiration?
