The ruling on one who remembers after performing wudu' that he did not wipe over his head

Question:
The questioner asks: What should I do if I performed wudu' and, when I finished, I remembered that I had not wiped over my head? Do I have to repeat the wudu' because order is a condition in wudu', or do I just wipe over my head? Please advise us, may Allah reward you with good.

Answer:
If he remembers that he did not wipe over his head and the time was recent, and the moisture of the wudu' is still present, he wipes over his head, washes his feet, and completes his wudu' because of the continuity. As for if the time has passed and the limbs have dried, he repeats the wudu' from the beginning because continuity is obligatory. However, what we advise is that one should not engage with doubts and illusions, especially after finishing the wudu'. Doubts after performing the act of worship and finishing it do not affect the ruling. But if he is certain that he did not wipe over his head, then it is as we mentioned previously. And Allah knows best.
