Salaah

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?

Q: Should you make sajda sahw if you read surah 110 in the first rakat and any earlier surahs in subsequent rakats?

Q: Kindly advise with regards to the following:

1. I woke up for fajr and there was only enough time to read my fardh. Can I read my sunnats after sunrise?
2. When I am a‎​ musaafir is it better for me to read my sunnats or not?
3. The two sunnatul muakadah after maghrib, is it part of awabeen or is awabeen 6 seperate rakaats?

Q: One person said: "as praying in congregation is a strong sunnah, and although its intentionally abandoning is makruh tahrimi , the ulama said its repeating is sunnah." Does this mean if some does pray at home intentionally then it is sunnah for him to repeat the same salaah after he has prayed?

Q: In a answer i read that if someone forgets one of the shurut of salaah such as having wudhu, facing qibla,  and prays, then if he remembers before the time of that prayer expires it is fard to reap it, but if he remembers after the has expired it is mustahab to repeat. Please give your input.

Q: A person does forget one the fard acts of salaah and remembers this after the time for that prayer expired. A fatwa was writing that is mustahab to repeat the prayer. Pleasr give your input.

Q: A person forgets to make sajdah sahw, is it wajib for him to repeat the salaah?
