Abdullah ibn Umar radiallahu anhum reported from his father that while he was addressing the people on Friday (sermon), a person, one of the Companions of the Messenger of Allah peace be upon him, entered (the mosque). Umar said to him loudly:
What is this hour (for attending the prayer)? He said: I was busy today and I did not return to my house when I heard the call (to Friday prayer), and I did no more but performed ablution only. Upon this Umar said: just ablution! You know that the Messenger of Allah peace be upon him commanded (us) to take a bath (on Friday).
