Umm Salama (Allah be pleased with her) reported that Allah's Messenger (ﷺ) married her, and he (the narrator) made mention of so many things in this connection (and one of them was this) that he said: If you desire that I spend a week with you, I shall have to spend a week with my (other) wives, and if spend a week with you, I shall have to spend a week with my (other) wives.
How the Prophet ص modelled this behaviour here
Justice & Fairness
“If you desire that I spend a week with you, I shall have to spend a week with my (other) wives”
Treats his wife (and co-wives) justly and equitably; honors her rights and gives her what is due without wronging her.
