The Messenger of Allah ﷺ marched toward Hunayn. The narrator mentioned the hadith, which included the following.Then the Messenger of Allah ﷺ sent word to Safwan bin Umaya, asking him for some coats of mail he had, a hundred of them, along with the equipment needed to use them.Safwan asked, "Is this a forced seizure, Muhammad?"He replied, "No, it is a guaranteed loan, which we will return to you."
أن رسول الله ﷺ سار إلى حنين. فذكر الحديث وفيه: ثم بعت رسول الله ﷺ إلى صفوان بن أمية فسأله أدرعا عنده مائة درع وما يصلحها من عدتها. فقال: أغصبا يا محمد؟ فقال: بل عارية مضمونة حتى نؤديها عليك.
Reported by Hakim (3/48-49), and from him Bayhaqi (6/89), via the route of Ibn Ishaq, who said, Asim bin Umar bin Qatada narrated to me, from Abdul-Rahman bin Jabir, from his father Jabir bin Abdullah, who mentioned it. Hakim said, "Its isnad is sahih." Its isnad is hasan because of Muhammad bin Ishaq, who has explicitly stated that he heard it directly.Abu Dawud (3562) also reported it through several routes from Yazid bin Harun, who said, Sharik narrated to us, from Abdul-Aziz bin Rafi, from Umaya bin Safwan bin Umaya, from his father, that the Messenger of Allah ﷺ borrowed some coats of mail from him on the day of Hunayn. He asked, "Is this a seizure, O Muhammad?" The Messenger of Allah replied, "No, rather a guaranteed loan." In this chain, Umaya bin Safwan is unknown. Ibn Hajar mentioned nothing about him in his Tahdheeb except that two people narrated from him, and in Taqreeb he said, "Acceptable," meaning when corroborated. And indeed he has been corroborated.Sharik is Ibn Abdullah the judge, who was weak in memory. Through his route it was reported by Ahmad (15302), Daraqutni (3/39), and Hakim (2/47), and from him Bayhaqi (6/89). Hakim passed over it in silence, but Sharik has also been corroborated.Abu Dawud (3563) reported it from the hadith of Jareer, from Abdul-Aziz bin Rafi, from some people of the family of Abdullah bin Safwan, that the Messenger of Allah ﷺ said, "Safwan, do you have any weapons?" He said, "As a loan or as a seizure?" He said, "No, rather as a loan." So he lent him between thirty and forty coats of mail. The Messenger of Allah ﷺ then went out to fight at Hunayn, and when the polytheists were routed, Safwan's coats of mail were gathered, and some of them were found missing. The Messenger of Allah ﷺ said to Safwan, "We have lost some of your coats of mail. Shall we compensate you for them?" He said, "No, O Messenger of Allah, for today there is in my heart what was not there that day." In this chain there are unidentified people.It has another corroborating narration, which is what Abu Dawud (3564) also reported, via the route of Abu Ahwas, who said, Abdul-Aziz bin Rafi narrated to us, from Ataa, from some people of the family of Safwan, who said, The Prophet ﷺ borrowed... and he mentioned it with the same meaning. This too contains unidentified people.It has another isnad as well, which is what Bayhaqi (6/89-90) reported from the hadith of Ibn Wahb, who said, Anas bin Iyad al-Laythi informed me, from Jafar bin Muhammad, from his father, that Safwan bin Umaya lent the Messenger of Allah ﷺ weapons, eighty coats of mail, and he mentioned the hadith. Bayhaqi said, "Some of these reports, even though they are mursal, are strengthened by their supporting narrations, together with the connected narration mentioned before," meaning by that the hadith of Jabir.It also has a supporting narration from Ibn Abbas, reported by Daraqutni and Hakim, and from him Bayhaqi, but it contains Ishaq bin Abdullah, whose hadith is abandoned. It has another supporting narration from Amr bin Shuayb, from his father, from his grandfather, but this too is daif. See its takhrij in Minna Kubra (5/371).As for Bukhari, may Allah have mercy on him, it seems he considered that there is inconsistency in it, since he mentioned the various isnads without giving preference to any, as is his usual practice. See Tarikh al-Kabir (2/8).
