If you missed it due to oversleep and not intentionally then you can make it up as soon as you get up. First you need to make up the missed prayers of the day in order then you can pray isha.

sheikh when i oversleep the whole day and missed dhur, asar and magrib prayers , and wake up in isha prayer time?? wot could b done at that time than? i have heard hadeeth that the minute u wake up is time for ur missed prayers but ,if 3 prayers missed together and i wake up in isha prayer time? should i offer isha 1st or missed salat ? and how 3 prayers are prayed to overcome major sin.
