Abu Hurairah reported,

The Messenger of Allah ﷺ met me while I was in a state of major ritual impurity. He took my hand, and I walked along with him until he sat down. I slipped away, went to my quarters, performed the bath, and then returned while he was still seated.He asked, "Where were you, Abu Hurr?"I told him.He said, "Glory be to Allah, Abu Hurr! The believer does not become impure."In another narration, "The Muslim does not become impure."

Sahih

عن أبي هريرة قال

لقيني رسول الله ﷺ، وأنا جنب، فأخذ بيدي، فمشيت معه حتى قعد، فانسللت فأتيت الرحل فاغتسلت، ثم جئت، وهو قاعد، فقال: أين كنت يا أبا هر؟ فقلت له. فقال: سبحان الله يا أبا هر إن المؤمن لا ينجس. وفي رواية: إن المسلم لا ينجس.
