Generally people take it as their right to offer Khada salaat, without being feeling that they have missed Fard salaat(to offer it in its time limit).
Answer:
Shari’ah has emphasised performing of Fardh Salaat on time. To deliberately
miss performing Salaat at its prescribed time is a sin. However, if one has
missed performing Salaat on time, due to reasons beyond one’s control, then
only Qadhaa Salaat should be performed.
