From Sahih Muslim (Hadith 537):
Hammam b. Munabbih who is the brother of Wahb b. Munabbih said:This is what has been transmitted to us by Abu Huraira from Muhammad, the Messenger of Allah (ﷺ) and then narrated a hadith out of them and observed that the Messenger of Allah (ﷺ) said: The prayer of none amongst you would be accepted in a state of impurity until he performs ablution
