Salaah

Inaudible Dua after Salaah

Q: I would like to know the ruling concerning dua after the congregation in the masjid. Should it be done audibly or should it be done inaudibly. Some people take offence at the fact that in certain masjids the day after congregation is made inaudible and they feel that because it is a congregation we should make the dua are similarly for everybody in an audible voice.

Qadha namaaz

Q: If anyone starts to offer 5 times namaz at any time of his life, so is it mandatory for him to offer all the due salats (Qaza-e-umri) first, which he has not been prayed since he was 12 years old?
