If someone inadvertently (sahwan) starts performing the ʿaṣr prayer before he has performed the ẓuhr prayer and realises this mistake in the middle of the prayer, he must change his intention to ẓuhr prayers, i.e. he must make the intention that whatever I have performed until now, and whatever I am performing right now, and whatever I will perform, is all part of the ẓuhr prayer. After completing the prayer, he must perform the ʿaṣr prayer.
[1] The legal midday is defined as the passing of the midway point of the day. For example, if the day is twelve hours long, the legal midday is after the passing of six hours from the time of sunrise. If the day is thirteen hours long, the legal midday is after the passing of six and a half hours from the time of sunrise.
