Salaah

Q: Can a person making ruku and sajda follow an Imam making salah with signs in a nafl salah?

Q: I have read that four rakaats (sunnat-e-muakkadah) before Zuhr salaah are equivalent in reward to Tahajjud salah. Is this proven from the Hadith?

Q: I have a question with regards to the wording of Dua-e-Qunoot according to the Hanifi Mazhab. The words ونتوكل عليك (wanatawaku alaika). Is it found in any Hadeeth? If not, would it be preferable to omit these words and suffice with the wording that we find and the Ahadeeths?

Q: I'd like to know if it's true that it's good to change places when we do salaah, because on the day of judgement, all these places where we did salaah will testify for us? For example, in a same home, I do fajar in the bedroom, zohar in another room and so on? Please enlighten me on this subject.

Q: What are the dua's whilst in sajdah?

Q: Will my salaah be valid behind an Imaam who makes masah over ordinary, cotton socks?

Q: Which salaah sould be performed last, witr or tahajud? I've now heard that the last namaaz has to be witr.

Q: A masbooq makes both salaams with the Imaam and then realizes that he is a masbooq. How should he complete his salaah?

Q: If I forgot to add a surah after surah Fatihah in the Fard prayer that has 4 rakaat, do I make this up by reading surah after surah fatihah in the 3rd rakaat or 4th rakaat? Do we have a choice of choosing 3rd or 4th rakaat? Of course, we still have to do sajdah sahw.

Q: When I do a long sajdah I sometimes forget if it is the first sajdah or the second sajdah. What should I do in this situation?
