The Messenger of Allah ﷺ said, "The best of you is the one who is best to his family, and I am the best of you to my family. When your companion dies, leave him be."
قال رسول الله ﷺ: خيركم خيركم لأهله، وأنا خيركم لأهلي، وإذا مات صاحبكم فدعوه.
Tirmidhi (3895) narrated it, and Ibn Hibban (4177) and Abu Naeem in al-Hilya (7/138) graded it sahih, all of them through the hadith of Muhammad bin Yusuf, from Thawri, from Hisham bin Urwa, from his father, from Ayesha, and he related it. Tirmidhi said, "This is a hasan gharib sahih hadith from the hadith of Thawri. Very few narrated it from Thawri." He also said, "This has been narrated from Hisham bin Urwa, from his father, from the Prophet ﷺ, as a mursal narration." End of quote. Abu Naeem said, "Firyabi narrated it alone from Sufyan." I say, it is as he said, except that Firyabi is Muhammad bin Yusuf, who is thiqa, and Nasai declared him thiqa. Ibn Adi said, "He has individual narrations from Thawri, he has many hadiths from Thawri, and Firyabi is placed ahead of a group such as Abdul-Razzaq and his peers in relation to Sufyan Thawri. They said, Firyabi had greater knowledge of Thawri than they did." Dhahabi in al-Mizan, commenting on Ibn Adi's statement, said, "Because he accompanied him for a long period, it is not to be denied that he would narrate alone from that ocean of knowledge."Of similar meaning is what was narrated from Ibn Abbas, from the Prophet ﷺ, who said, "The best of you is the best of you to his family, and I am the best of you to my family." Ibn Majah (1977) narrated it, as did Tahawi in Mushkil (2523) and Hakim (4/173), all of them through the hadith of Abu Asim, from Jafar bin Yahya bin Thawban, from his uncle Umara bin Thawban, from Ata, from Ibn Abbas, and he related it. Tahawi added at the beginning of the hadith that some men sought the Messenger of Allah's ﷺ permission to beat their wives, and he permitted them. Then he heard a sound and said, "What is this?" They said, "You permitted the men to beat their wives." So the Messenger of Allah ﷺ said, and then he related the hadith.In this chain is Jafar bin Yahya bin Thawban, whom Ibn Madini described as, "Unknown, no one narrated from him except Abu Asim," and Ibn Qattan Fasi said, "His condition is unknown." Also in the chain is Umara bin Thawban, a Hijazi, from whom no one narrated except his nephew Jafar bin Yahya bin Thawban. Ibn Madini said, "No one narrated from him except Jafar bin Yahya," and Abdul-Haqq said, "He is not strong," but Ibn Qattan rejected this and said, "Rather, his condition is simply unknown." As for Ibn Hibban, he mentioned both of them in al-Thiqat, following his practice of declaring unknown narrators thiqa, and he included this hadith in his Sahih (4186) through this same route.Also of similar meaning is what was narrated from Abdullah bin Amr, who said, the Messenger of Allah ﷺ said, "The best of you are the best of you to their wives." Ibn Majah (1978) narrated it from Abu Kurayb, who said, Abu Khalid narrated to us, from Amash, from Shaqiq, from Masruq, from Abdullah bin Amr, and he related it. Abu Khalid is Sulayman bin Hayan Azdi Kufi, one of the narrators found in the six major collections, though he used to make mistakes. Ibn Adi said, "He has sound hadiths, but his errors stem from poor memory, so he makes mistakes and errs, though at his core, as Ibn Main said, he is truthful and there is no harm in him." What is beyond doubt is that he erred in this particular hadith, for a group of narrators reported it from Amash with his chain and said instead, "Indeed, the best of you are those best in character," and this version is found in the Sahihayn. Bukhari (3559) and Muslim (2321) narrated it, and in Muslim it comes from the hadith of Abu Khalid himself with this same wording.Also on this subject is what was narrated from Sulayman bin Amr bin Ahwas, who said, my father told me that he witnessed the Farewell Pilgrimage with the Messenger of Allah ﷺ. He praised Allah and extolled Him, then spoke and admonished the people, and within the hadith he mentioned an account, saying, "Take heed, and treat women well, for they are captives in your care. You have no right over them beyond that, unless they commit a clear act of indecency. If they do so, then forsake them in their beds and strike them without causing severe harm. If they then obey you, do not seek any means against them. Take heed, you have rights over your wives, and your wives have rights over you. As for your right over your wives, they must not allow onto your bedding anyone you dislike, nor permit into your homes anyone you dislike. And their right over you is that you treat them well in providing their clothing and food." Tirmidhi (1163) and Ibn Majah (1851) narrated this, with the wording belonging to both of them, and Abu Dawud (3332) and Ahmad (15507) both narrated it in abridged form, all of them through the route of Sulayman bin Amr, from his father Amr bin Ahwas, and he related it.Sulayman bin Amr bin Ahwas was declared thiqa by no one except Ibn Hibban, following his usual practice, and he is "unknown" as Ibn Qattan said. In al-Taqrib he is described as "acceptable," meaning when corroborated, but I have not found any corroboration for him, so his hadith is weak in strength.
