Q: What is the benefit of moving from one's place after the fardh salaah before the sunnah?

Q: Is there any Hadith that states why there are 2 sajdahs in Namaaz and only one ruku?

Q: In the hanafi mazhab, what is the status of making a single sajdah out of namaaz. I have seen many people do this. I have tried to explain to some that a single sajdah should not be made rather a coplete 2 raka'aat should be read but they don't understand. The reply they give is, "I cannot make a sajdah of shukr?" Should they still be told? And if so, how should they be explained?

Q: Is it permissable to pray in multi faith prayer rooms, such as the ones they usually have at airports? These rooms are mostly used by Muslims but also some non-Muslims use them for praying and apart from Islamic material they also contain bibles and books of other religions. The question came to my mind since, if I remember it correctly, we are not allowed to enter into buildings of worship of other religions?

Q: Someone asked me the following question saying that he was put in a situation when asked as to what is the reason for there being two sajdahs in each rak'at of namaaz?

Q: Our work has a makeshift prayer room with a toilet and hand basin in it - is this acceptable? The room is alongside the female toilets and a meeting room and noises carry through the wall into the prayer room - is this a problem? I use a disabled toilet close to the prayer room (10 metres) and have used a plastic bottle for cleansing. The company has taken the bottle away as they say it is a safety problem. I suggested they instal a hand held bidet (like a shower hose) to remove safety problem.  But they want me to use another disabled toilet that is further away (more than 50 metres and through many doors) because they don't want to upset disabled people. How far away should cleansing be from the prayer room?

Q: In salah, can we repeat the translation of holy quran in the heart for the sake of khushu n khuzu?
