Witr Salaah

Q: Are there two Witr namaaz's per day? ie. 1. Esha - 3 rakaats Witr Wajib 2. Tahajjud - 2 rakaat followed by 1 rakaat Witr? Should both be read every night or are they the same and only one should be read?

Q: Can we offer Tahajjud Salaah after we have offered our Witr Wajib or we should not offer our Witr Wajib before Tahajjud?

Q: Should one read Bismillah Hir Rahmanir Rahim before reciting Duaa-e-Qunoot in the Witr Salaah?

Q: In Deoband the Ulama say witr prayer in Kaaba is not valid and we need to repeat it as it remains due. Is this correct? Also, can one pray 1 or 3 or 5 rakats in witr?

Q: I usually read my witr salaah at the time of tahajjud, after the tahajjud salaah. However, sometimes by the time I finish my witr the fajr time has set in. Will this be regarded as qadha? Will I have to repeat it? Will it be better for me to read the witr before sleeping?

Q: Should we as Hanafis recite a Durood after Dua Qunoot?

Q: Are hanafis allowed to follow a shafi Imaam in witr during Ramadan? (The scholar claims it is allowed and its to bring the community together.)

Q: If one does not know dua e qunoot what should he recite in place of it?

Q: I have deep doubts regarding the authenticity of witr salaah of the Hanafi Madhab. I have asked a Sheikh and he told me not to read in that manner. Can you mention to me few authentic Hadeeth regarding this issue. 

Q: Must one make sajda-e-sahw if one misses the ruku in the last raka'ah in witr?
