The Messenger of Allah ﷺ said, "Whoever performs ablution on Friday, that is good and sufficient, but whoever bathes, that is better."
قال رسول الله ﷺ: من توضأ يوم الجمعة فبها ونعمت، ومن اغتسل فهو أفضل.
Abu Dawud (354), Tirmidhi (417), and Nasai (1379) all narrated it through various chains from Qatada, from Hasan, from Samura, mentioning the same. Its isnad is sahih, and although Qatada was known for tadlis, Shuba narrated from him in some of its chains, and he is the one who said, "I have spared you the tadlis of three narrators, Amash, Abu Ishaq, and Qatada." As for Hasan, there is disagreement about whether he actually heard from Samura, and the position I have preferred, following Ibn Madini, Bukhari, and others, is that he heard from him without restriction. Ibn Daqiq Eid said in al-Imam, "Whoever holds that Hasan's narration from Samura was a direct hearing considers this hadith sahih." Ibn Mulaqqin reported that Abu Hatim graded this hadith sahih through both of its paths, meaning the connected and the disconnected versions, and his son reported from him that he said, "They are both sahih." See al-Badr al-Munir (4/651). Ibn Khuzayma (1757) also graded it sahih, narrating it through the path of Shuba, from Qatada, with the same wording.Tirmidhi said, "The hadith of Samura is a hasan hadith, and some of Qatada's companions narrated this hadith from Qatada, from Hasan, from Samura, while others narrated it from Qatada, from the Prophet ﷺ, as a mursal narration." I say, those who narrated it as connected are trustworthy narrators, so the narration of those who narrated it as mursal does not harm it.As for what was narrated from Bara bin Azib, who said that the Messenger of Allah ﷺ said, "It is a duty upon the Muslims to bathe on Friday, and each of them should apply some of his family's perfume, and if he cannot find any, then water is his perfume," this is daif. Tirmidhi narrated it (528) from Ali bin Hasan, who said, Abu Yahya Ismail bin Ibrahim Taymi narrated to us, from Yazid bin Abu Ziyad, from Abdul-Rahman bin Abu Layla, from Bara, mentioning it.This isnad is daif. Ismail bin Ibrahim Taymi is daif, though he was not alone in narrating it, for Tirmidhi (529), Ahmad (18488), and Tahawi in Sharh Maani al-Athar (1/116) all narrated it through the path of Hushaym, from Yazid bin Abu Ziyad, with the same wording. Hushaym explicitly stated that he heard it directly in Tahawi's narration, but the whole chain revolves around Yazid bin Abu Ziyad, who is the Hashimi, their freed client from Kufa, daif, who grew old and his memory changed, so he began being fed narrations by others, and he was a Shia.The hadith has other chains of transmission, but they all revolve around Yazid bin Abu Ziyad, and this is why Tabarani said in Mujam al-Awsat (813), "This hadith was not narrated from Bara except through this isnad, Yazid bin Abu Ziyad narrated it alone."
