Salaah

Q: Is Sajdatus-sahw necessary if someone recited Quran after rising from ruku'? 

Q: Namaz behind such imam: 

If there's a Barelvi masjid in my area and they say the following before or after azan: "assalatu wassalamu alaika ya rasulullah wa ala alika wa ashabika ya noor Allah" 

Can I pray behind them and if not, should I repeat every prayer behind them?

Q: A person wakes up in need of a Fardh Ghusl 15 minutes before sunrise. There is no hot water and the person has chronic health issues. Using cold water will cause his health to deteriorate. It takes approximately 15 minutes to heat up sufficient water for Ghusl. If he waits, the time will expire and Fajr Salaah will become Qadha. What should be done in such a situation?

Q: 

1. If the latecomer joins the Imam in the first or final tashahhud for even a moment, then does the latecomer finish his tashahhud before rising up (for either the third unit, or to complete his missed units)? If the Imam rises quite soon after the latecomer joins him in the first tashahhud, then is it a factor that the latecomer may be behind the Imam? 

2. A latecomer makes the opening takbeer while the Imam is in the first tashahhud. If the Imam begins to rise for the third unit while the latecomer is going down, what does the latecomer do? 

3. A latecomer makes the opening takbeer while the Imam is in his final tashahhud. If the Imam says the first Salam while the latecomer is going down to join him, what does the latecomer do?

Q: Are women allowed to attend the masjid for 5 times daily salaah with congregation? Just like how in the western countries it's done?

Q: Is it sunnah for a lady to perform 2 rakaats in Masjid Quba on Saturday or is it sunnah only for men?

Q: I have a few questions about safr. 

1. What's the boundaries of Durban? Like a person leaving Overport, when will he start counting? And when returning if he stops in Pinetown, will he read qasr? And what about if he stops in Sherwood? 

2. In each direction where will he read qasr? So if he is going north up the coast where will he be able to read qasr? Going south on the n2? And going north on the N3? 

Basically what's the boundaries of Durban.

Q: I have heard that one should pray Qadha prayer in solitude so that it should not be revealed to anyone that one is praying Qadha prayer. Is this true? 

If so, then there is a problem that in a house where one does not get solitude and it is not possible in the mosque, then what should one do in such a case? 

Then can one pray Qadha prayer in front of the family members or in front of everyone in the mosque.

Q: Can chaast salaah still be performed at 11 am in the morning? I get my break from work at that time but is it permissible at that time?
