From Sahih Muslim (Hadith 824):
Abu Huraira reported that he met the Messenger of Allah (ﷺ) on one of the paths leading to Medina in a state of (sexual) defilement and he slipped away and took a bath. The Apostle of Allah (ﷺ) searched for him and when he came, he said to him:0 Abu Huraira, where were you? He said: Messenger of Allah, you met when I was (sexually) defiled and I did not like to sit in your company before taking a bath. Upon this the Messenger of Allah (ﷺ) said: Hallowed be Allah, verily a believer is never defiled
