Salaah

How should one reply to the Azaan if one forgot to reply from the beginning?

Q: If a person did not repeat the words of the Azaan immediately after the muazzin but only remembered at the end of the azaan at the time when the muazzin reached Hayya Alal Falaah, can he repeat the words from the beginning of the azaan or he should only repeat the words of the muazzin from hayya alal falaah?

Question relating to Qadha Salaah

Q:

  1. What is the procedure of doing missed Qada namaz of last 10 years, approximately 500 salaahs?
  2. What will be intention?
  3. How many Rakat for each salat?
  4. Is there qada for witr?
  5. As I have lots of missed namaz, can I do qada salat instead of doing any nawafil as well tahajud? Please explain in detail so that I can do it.

Will one become a kaafir if he does not perform Salaah?

Q: The Prophet (Sallallahu Alayhi Wasallam) once said, that the one who leaves or abandons prayer is a kaafir. So what if one who has parents that are from a Muslim background, (practising or otherwise), has never prayed the 5 prayers out of laziness or other reasons, but believes in Allah and His Messenger; is he/she still considered a kaafir? I mean, will they still be Muslims, but only called non-practising Muslims due to them not praying? Also, what if they try to pray sporadically, but without wudu or without saying the prayer words properly or without intention, only to please others (while they still know this is wrong); are these people still considered non-practising Muslims, even though they still believe wholly in Allah and His Messenger? How is a Muslim defined in this case? The reason why I am asking this, is because I heard that because one has either left the prayer or has never properly prayed to begin with, is not even considered a Muslim, regardless of whether he/she believes in Allah and His Messenger or not?  Is this correct?
