All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
We have not across a Hadeeh with this wording, neither in Sunan At-Tirmithi nor in any other books of Hadeeth. However, if you mean the Hadeeth which reads: “The best amongst yourselves are the best to their wives, and I am the best to my wives.”; then this is a Saheeh [sound] Hadeeth narrated on the authority of ‘Aa’ishah and reported by At-Tirmithi, and it was also reported by Ibn Maajah on the authority of Ibn ‘Abbaas .
Indeed, many authentic Ahaadeeth were reported about the virtues of treating women (wives) in a good manner and this is something ordained by the Sharee’ah. Even the Quran mentioned this, as in the saying of Allaah (which means): {And live with them in kindness. For if you dislike them — perhaps you dislike a thing and Allaah makes therein much good.} [Quran 4:19]
Allaah Knows best.
