the Prophet saying: "Whoever comes on Friday, then let him perform Ghusl."
Jami` at-Tirmidhi Book 4, Hadith 5
← Previous Hadith "Allah's Messenger said: The best day that the sun has risen upon is Friday. On it Adam was created, on it he entered Paradise, and on it, he was sent down from it. And in it there is an hour in which the Muslim worshipper would not stand in Salat, asking Allah for anything except that He would give it to him.'" Abu Hurairah said: "I met Abdullah bin Salam, and I mentioned this Hadith to him. He said: 'I am more knowledgeable about that hour.' So I said: 'Inform me about it, and do not keep any of it from me.' He said: 'It is after al-Asr until the sun has set.' I said: 'How can it be after Al-Asr when Allah's Messenger said: ' the Muslim worshipper would not stand in Salat.' And that is a time that prayer is not performed in?" So Abdullah bin Salam said: 'Didn't Allah's Messenger say: "Whoever sat in a gathering awaiting the Salat then he is in Salat"? I said: 'Of course.' He said: 'Then that is it.'"
