Question: As I am praying my Qaza e umari namaz daily for one day at night I start in this order zohr,Asar,Isha,magrib,fajr but today some one told me that my magrib and isa namaz is invalid due wrong sequence. Please answer at your earliest convenience. Should I have to give qaza for all magrib and isha namaz.

no problem
but from now care for sequence.
