The Messenger of Allah ﷺ said, "The best charity is that given to a relative who harbors hidden enmity toward you."
قال رسول الله ﷺ: أفضل الصدقة على ذي الرحم الكاشح.
Hakim narrated it (1/406), and Bayhaqi narrated it from him (7/27), through the route of Abdul-Razzaq, who said, Maamar informed us, from Zuhri, from Humayd bin Abdul-Rahman, from his mother Umm Kulthum bint Uqba, and he mentioned it. Hakim said, "Sahih according to the criterion of Muslim." Tabarani narrated it in Al-Kabir (8/25), and Humaydi in his Musnad (328), and Ibn Khuzayma (23), all of them through the route of Sufyan bin Uyayna, from Zuhri with his chain, similarly. Except that Humaydi said, "Sufyan narrated to us, saying, they informed me from Zuhri." Sufyan said, "I did not hear it from Zuhri." Perhaps he had not heard it at first, then later it became possible for him to hear it from him, or those from whom he heard it were known to him, and so he sometimes narrates through an intermediary and sometimes without one.Munziri mentioned it in Targhib wal-Tarhib (1343) and said, "Tabarani narrated it in Al-Kabir, and its narrators are the narrators of the Sahih, and Ibn Khuzayma and Hakim graded it sahih." Haythami also mentioned it in Al-Majma and said, "Its narrators are the narrators of the Sahih."Of similar meaning is what was narrated from Hakeem bin Hizam, that a man asked the Messenger of Allah ﷺ which charity is best, and he said, "That given to a hostile blood relation." Abdullah bin Ahmad narrated it in the Musnad of his father (1523), saying, I found in my father's book, in his own handwriting, Saeed, meaning Ibn Sulayman, narrated to us, Abbad, meaning Ibn Awwam, narrated to us, from Sufyan bin Husayn, from Zuhri, from Ayub bin Bashir Ansari, from Hakeem bin Hizam, and he mentioned it.Its chain is daif because of Sufyan bin Husayn, who is Wasiti, trustworthy by the agreement of the people of knowledge, except in the case of Zuhri, for he is daif regarding him. So said Ibn Main, Ahmad, Nasai, and others. Ibn Hibban mentioned him in Ath-Thiqat (6/404) and said, "As for his narration from Zuhri, it contains confusions that must be avoided, but he is trustworthy in other than that." And he said in Al-Majruhin, "He narrates from Zuhri things that are inverted, because Zuhri's manuscript became mixed up for him."I say, the corroboration of Hajjaj bin Artah for him, from Zuhri, is of no benefit, for Hajjaj is daif, and he is not known among the companions of Zuhri. Tabarani narrated it through his route in Al-Kabir (3126). So do not be deceived by the statement of Haythami in Al-Majma (3/116), "Ahmad and Tabarani narrated it, and its chain is hasan."As for his statement, "Ahmad narrated it," perhaps he is referring to what Imam Ahmad narrated (23530), from Abu Muawiya, who said, Hajjaj narrated to us, from Zuhri, from Hakeem bin Bashir, from Abu Ayub Ansari, and he mentioned the hadith similarly. All of this comes from the confusions of Hajjaj bin Artah.Daraqutni said in Al-Ilal (15/360–361), "Hajjaj bin Artah narrated it from Zuhri. Once he said, from Hakeem bin Bashir, from Abu Ayub Ansari. And another time, from Ayub bin Bashir, from Hakeem bin Hizam, and neither of the two is preserved." As for his statement in another place in Al-Ilal (6/119), "No one narrated from Zuhri except Hajjaj, and it is not established," I have seen that Sufyan bin Husayn also narrated it from him, and Daraqutni did not point to this narration.His statement, "hostile," means one who is cutting off and hateful, and it is also said that it means the enemy who conceals his enmity.
