Is the woman who delays 'Asr prayer until two and a quarter hours after the Adhan, due to her sleep, sinful, knowing that this happens most days?

Scholars have agreed on the obligation of performing prayer within its prescribed time, as Allah says: "Indeed, prayer has been decreed upon the believers a timed ordinance." It is not permissible to intentionally delay it beyond its time, except for an excuse, such as a menstruating woman who becomes pure, or a disbeliever who embraces Islam, or a sleeper who awakens, or a sick person who recovers. And whoever catches one unit (rak'ah) of the prayer before its time expires, has indeed caught it within its time.
