Does vadu get invalid if one person sees the aurah of His wife?.
Wudoo’ is not invalidated by that. We have already listed, in the answer to question no. 14321, the things that invalidate wudoo’. A man’s seeing his own ‘awrah or that of someone else is not one of them.
The Standing Committee was asked (5/270): is wudoo’ invalidated simply by looking at naked men and women, and is wudoo’ invalidated if a man looks at his own ‘awrah? They replied:
Wudoo’ is not invalidated simply by looking at naked men and women, or by looking at one’s own ‘awrah, because there is no evidence to that effect.
They were also asked (5/283): can a Muslim touch the Mus-haf or pray if he has looked at his own ‘awrah when he was doing wudoo’? They replied: Yes, looking at the ‘awrah is not one of the things that invalidate wudoo’.
