The one who consumes usury, the one who pays it, the two witnesses to it when they know what it is, the woman who tattoos and the woman who has herself tattooed, the one who withholds charity, and the one who reverts to Bedouin life after making the Hijrah, all of these are cursed on the tongue of Muhammad ﷺ on the Day of Resurrection.
آكل الربا ومؤكله وشاهداه إذا علماه، والواشمة والمستوشمة ولاوي الصدقة والمرتد أعرابيا بعد الهجرة ملعونون على لسان محمد ﷺ يوم القيامة.
Ibn Khuzayma (2250) and Hakim (1/387-388) both narrated it, via Ibn Isa, from Amash, from Abdullah bin Mura, from Masruq, who said, Abdullah said, and then mentioned it.Hakim said, "Sahih according to the criterion of Muslim, for Muslim relied on Yahya bin Isa Ramli as a source, though the two of them did not include it in their Sahihs."I say, its isnad is hasan because of the discussion surrounding Yahya bin Isa. Although he is among the narrators used by Muslim, there is disagreement about him. Ibn Main, Nasai, and others declared him daif, while Ahmad spoke favorably of him, and Ibn Hibban and Ajli listed him among the trustworthy narrators. So his hadith is hasan.However, Nasai (8/147), Imam Ahmad (3881), and Ibn Hibban in his Sahih (3252) all narrated it through routes going back to Amash, from Abdullah bin Mura, from Harith bin Abdullah, that Ibn Masud said, and then mentioned it.Harith bin Abdullah is al-Awar, who is very daif.So one wonders, did Abdullah bin Mura narrate it by two separate routes, or did Amash conceal a defect in the chain? For Nasai narrated it via Shuba, from Amash, who said, "I heard Abdullah bin Mura narrating from Harith, from Abdullah."He also narrated it through the route of Husayn, Mughira, and Ibn Awn, from Amir Shaybi, from Harith, from Ali.However, it appears in Musnad Imam Ahmad that he, meaning Amash, said, "I mentioned that to Ibrahim," meaning Ibrahim bin Yazid Nakhai, "and he said, 'Alqama narrated to me, saying, Abdullah said,'" and then he mentioned part of the hadith. This isnad is sahih. If this is confirmed, then what was narrated from Harith bin Abdullah al-Awar causes no harm.
