Salaah

Q:

1. Is the Witr prayer compulsory?

2. Is it true that without Witr prayer Isha prayer is not complete?

Q: I read a hadith that, the Prophet (sallallahu alaihi wasallam) said: “Whoever misses the Asr prayer, then it is as if he has been robbed of his family and his wealth.” (Al-Bukhari 552).

And... In another narration by Al-Bukhari and others: “Whoever abandons the ‘Asr prayer, his deeds of worship become void.”

I am 23 years old and a practicing Muslim since I was a kid. Recently I missed my Asr Salah. I didn't sleep all day/night, So I was very tired. During the afternoon time slept and missed Asr salah though I was aware that it was Asr time. I kept delaying the time and eventually missed it. Now I am scared if all of my deeds have been void. I prayed the Qada' Salah.

But there is also a hadith that says, Anas reported that the Prophet (sallallahu alaihi wasallam) said, "Whoever forgets a prayer should pray it when he remembers it, and there is no expiation (kaffarah) for it save that." Related by al-Bukhari and Muslim.

And... The Prophet (sallallahu alaihi wasallam) said: “The Pen has been lifted from three: from the sleeper until he awakens, from the child until he reaches puberty and from the insane person until he comes to his senses -- or until he comes round.” Narrated by Abu Dawood (4403), al-Nasaa’i (3432) and Ibn Maajah (2041). Classed as saheeh by Shaykh al-Albaani in Saheeh Abi Dawood.

So, is all my deeds/prayers/amals has been invalid or not? I am confused.

Q: I traveled from Pakistan to Stretford UK where I intended to stay for less than 15 days and during these days will go for a day to Peterborough and come back and then after two days will go for two days to London and come back. Then I will move 15 miles away to Hazel Grove town and will stay there for 20 days. My question is that should I pray qasar salah or otherwise?

Q: I am in UAE. In one masjid while offering fajr Salah the imam was reciting some dua like qunoot followed by some other dua's and ended with durood on Nabi sallallahu alaihi wasallam.He did this after getting up from ruku in second rakaat. And the imam sahaab leads the fajr prayers in the same way everyday. Is there any Hadith proving this way.
