Travel costs;qadha salaah

Few months back I heard a Q&A of Mufti sahebs wherein it was said that qadha should be read over sunnat namaaz. My questions are as follows:
A) Does this apply to sunnat ghair muakkada only or either sunnat namaaz?
B) If I intend trying to cover up my lifes qadha, can I concentrate on fajr and zuhr only and then move on to asr and so forth?
C) if (B) is yes, will it be permissible for me to make one collective niyyat for all 2 and 4 rakats to be a qadha for fajr and zuhr (obviously with the exception of my normal farz namaaz)? Or do I have to make a niyyat before each qadha?
D) Will it be permissible to read tahajjud or must I read qadha during that time?
Jazak-Allah for your time.Please remember me in your duas.Was-salaam

  1. You heard wrongly. There is no Qadha for Sunnat, except for the Fajr ones if has to do so then it can be done before Zawal.
    b) Do one Salaat at a time – Zohr then Asr etc.
    c) do one Salaat at a time
    d) Read Salaat of Tahajjud then Qadha
