Q:

1. I have witnessed many Muslims standing up when they drink Zam Zam Water. Those who sit and drink are being ridiculed by many people and even Mullahs who justify that we must always stand up while drinking Zam Zam Water. 
2. I have also witnessed many people standing/walking while drinking water and eating dates in Haram Sharief in Makkah. But, the Sunnah of Rasul Allah Sallallaahu Alaihiwa Sallam is that we must always sit while drinking or eating. Please clarify in detail.

Q: It is understood that performing Salaah/Sajdah in a place with najaasat is impermissible, with or without Prayer mat. But, I have witnessed many Muslims offering Salaah on the floor at offices, at railway stations, inside the aircraft, in trains, on the roads, on the deck of a ship/boat, etc. These places are frequented by many people returning from the toilets with their footwear on, which has a lot of najaasat. Will Salaah not be invalid for those who pray at these places with najaasat? I have had many debates with these people who justify that their Salaah is valid in these places.
