I live in Europe and my work commute is long, the only prayer I have time to read on time are Fajr, Maghrib (in summers) and Isha. The rest I have to read as Kaza. Sometimes I am so out of energy that I cannot do it and so 4 out of 5 are missed.
My question is can I read kaza namaz next day for the previous day instead of feeling guilty? Is there any Hadith about people unable to perform Namaz on time and reading as soon as possible for missed one (like next day)
