Jabir b. 'Abdullah (Allah be pleased with them) reported that Allah's Messenger (ﷺ) sacrificed (animals) on behalf of his wives, and in the hadith transmitted by Ibn Abu Bakr (the words are): " A cow on behalf of 'A'isha on the occasion of the Hajj."
How the Prophet ص modelled this behaviour here
Generosity & Provision
“Allah's Messenger (ﷺ) sacrificed (animals) on behalf of his wives”
Generously provides for and maintains his wife and household; is openhanded with sustenance rather than stingy.
