Musannaf Ibn Abi Shayba 3:2652

Ali bin Hashim narrated to us, from Ibn Abi Layla, from Atiyyah, from Abu Sa’id, from the Prophet, may Allah bless him and grant him peace, who said: "Whoever performs ablution and performs the ablution well, then comes to the Friday (prayer) and does not engage in idle talk and does not act ignorantly, it will be an expiation for what is between it and the other Friday, and the five prayers are expiations for what is between them. And in Friday, there is an hour; no Muslim servant coincides with it and asks Allah for good, but He gives it to him."
