Ramadhaan & Fasting

Fasting on Mondays

Q: An Aalim says: Traditional Eid-e-Milad-Un-nabi is Bid'ah. It is not Islamically right. But, it is true that Rasulullah (Sallallahu Alayhi Wasallam) himself celebrates the days Modays keeping Fast since it was his birth day, day of Hijrat, day of getting Nabuwat etc. I would like to know, if it is correct and if so, can we keep fast on Mondays like our prophet (Sallallahu Alayhi Wasallam)?

Laylatul Qadr

Q: Some Ulama mention that layltul Qadr was experienced outside the last 10 nights of Ramadan. Is this proved by experience or Authentic narrations? If proven from Authentic narrations, Why is it only emphasized in the last ten nights of Ramadan? Is Laylatul Qadr on a specific night or it alternates every year? Is Laylatul Qadr specific to an individual or community on different nights or is it general for the entire mankind on that specific night?

Receiving the rewards for fasting on virtuous days

Q: I made a vow that if I commit a certain sin I will fast for 3 consecutive days. Unfortunately I fell in to this sin many times after so I have 27 fasts to keep. If I fast with the intention of these fasts on days that are virtuous to fast like the first 9 days of Zul HIjjah, 13 14 15 of each month will I receive the thawaab that comes with normally fasting on these days or will only my vow be carried out?
