Salaam all,
In light of this verse:
'O you who believe, do not approach the Salat while you are intoxicated, until you know what you are saying. Nor if you have had intercourse, unless traveling, until you bathe. And if you are ill, or traveling, or one of you has excreted feces, or you had sexual contact with the women, and could not find water, then you shall select from the clean soil; you shall wipe your faces and hands. God is Pardoning, Forgiving.' (Qur'an 4:43)
...it is quite commonly found that other factors are said to 'nullify' purity where wudhu has to be performed as a prerequisite for prayer. E.g. passing wind, whistling, listening to music, a man seeing a woman who isn't in hijab nullifies the purity of the woman...
Is there anything to warrant these claims?
