Witr is part of the night prayer, and it is Sunnah and it is the end of the night prayer, one Rak`ah with which one concludes the night prayers at the end, or in the middle, or at the beginning of the night after `Isha.

Du’a al-Qunut is recited in the last rak’ah of Witr prayer, after bowing. The formula of Du’a al-qunut was narrated by Abu Dawud, al-Tirmidhi, and al-Nasai.

It is permissible to pray Witr 3 rak’ahs with one salam, but it should be with only one tashahhud and not two, because if he does it with two tashahhuds, it will be like Maghrib prayer and the Prophet (peace and blessings be upon him) forbade making witr like Maghrib prayer.

The time of Duha prayer is from the time when the sun has risen to a certain height, until just before the time for Zhuhr prayer.

Al-qunut should come after the ruku` but if a person recites it before the ruku` that is OK. You should raise your hands to chest level and not raise them very much, and you should spread your palms (with hands together) and hold them facing up towards the sky.
