Salaah

Q: My question is that we read the Alhamdu shareef in our namaz. When we read namaz in jamaat then do we need to read the Alhamudu shareef or not? 

Q: Is it permissible to make esha early in shafi time if one is travelling similar to reading asar early in shafi time?

Q: Is it obligatory for a female to cover her head during the time of 'Azaan' when she is at home? If not then why muslim women act like this? 

Q: If a person was supposed to make Sajdah Sahw but forgot and made both Salaams, then what should he do? Can he make Sajdah Sahw immediately or should he repeat the Salaah?

Q: I heard that it is makrooh to perform Salaah behind an Imam who shaves his beard or trims it less than one fist? Is this true? If so, is it better to pray alone if there is no Imam with a Shar'ee beard present? Or is it not sinful to pray behind such an Imam?

Q: If I am travelling and the time of prayer is finishing and there is no way the bus can stop, can I pray in the bus only? Please explain in detail.

Q: In a four rakaat sunnah ghayr muakkad salaah or a four rakaat nafila prayed with one taslim, if one reads in the first tashahhud after the durood ibrahimiyyah a masnoon dua does this entail sajdah sahw? Or is this permissible?

Q: Do nafil prayers make up deficient fard prayers? Like one missed a pillar of fard salaah unknowingly, or does missing a pillar unknowingly not get one accounted on that?

Q: If someone sees the imaam after he has led the salaah wearing slippers with pigskin leather inside-soles. Did the pigskin leather inside-soles make the socks he was wearing impure? The salaah he led was it valid or invalid for everyone?

Q: A common issue which is observed in Masaajid is how musallees in the front rows exit while the musallees who arrived late are still performing their missed rakaats in the rows behind them. Can we walk in front or across them in order to exit?
