Umm Salama (Allah be pleased with him) reported that the Messenger of Allah (ﷺ) took an oath that he would not go to some of his wives for the whole of the month. When twenty-nine days bad passed he (the Holy Prophet) went to them in the morning or in the evening. Upon this it was said to him:Apostle of Allah, you took an oath that you would not come to us for a month, whereupon he said: The month may also consist of twenty-nine days
Scholarly Authentication
The label above is the grade most of these scholars gave, each scholar counted once — one dissenting opinion no longer speaks for all of them.

Each scholar's own wording:
Every narration in Sahih Muslim is accepted as Sahih (authentic) by the established status of the book.
