It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that Sayyiduna Umar (may Allah be pleased with him) was delivering the sermon on Friday, when a man (and according to another narration, Sayyiduna Uthman [may Allah be pleased with him] ) entered the mosque. Sayyiduna Umar (may Allah be pleased with him) asked: Why do you people delay in matters of prayer? He replied: As soon as I heard the call to prayer, I performed ablution and came. Sayyiduna Umar (may Allah be pleased with him) said: Have you not heard this hadith of the Noble Prophet (peace and blessings be upon him)? He (peace and blessings be upon him) said: "When any one of you comes (to the mosque) for Friday (prayer), he should perform ghusl (ritual bath)."
