It was narrated that ‘Ata‘ said:

We attended the funeral of Maimoonah, the wife of the Prophet (ﷺ), in Sarif, with Ibn 'Abbas. Ibn 'Abbas said: This is Maimoonah, so when you lift up the bier, do not shake it or make it wobble, because the Messenger of Allah (ﷺ) had nine wives and he used to divide his time between eight, and did not give a share of his time to one. ‘Ata‘ said: The one to whom he did not give a share of his time was Safiyyah.
