Does Seeing Wife's Awra Cancel Ablution?

What invalidates ablution, if a husband sees his wife's private parts? Quoted from islamqa.ca., ablution is not void for that reason. This has been explained in the answer to question no.14321, about the explanation of things that invalidate ablution. It is not mentioned there that seeing him as a husband to his private parts or someone else's private parts is a voiding of ablution.

Lajnah Daimah was once asked, 5/270.

Does it invalidate ablution if you just see a naked woman or man? And what invalidates the ablution of a husband who sees his wife's private parts?

They answered, "Wudhu is not invalidated simply because the person performing ablution sees a woman or sees a naked man, or simply sees his wife's private parts, because there is no argument about that."

Lajnah Daimah was also asked, 5/283, "Can a Muslim touch the mushaf or pray if he sees his aurat during ablution?

"Yes can. Seeing private parts does not invalidate ablution.” Allahu alam.
