As for the chains of transmission to Anas to which al-Hakim alluded, al-Khatib narrated them in al-Tarikh (3/49, 306; 13/127) through three routes from him. They are extremely weak, so there is no need to lengthen the discussion by documenting them. The hadith also has a supporting report from Abu Saʿid al-Khudri, attributed to the Prophet, to the same effect, but it is very weak. ʿAbd ibn Humayd narrated it in al-Muntakhab min al-Musnad (110/2) through Ibrahim Abu Ishaq, from Abu Nadrah, from him. This is a very weak chain of transmission. This Ibrahim was Ibn al-Fadl, and he is abandoned, as stated in al-Taqrib. In sum, the hadith is good, if Allah Most High wills, on account of the route of Baqiyyah which al-Diyaʾ narrated in al-Mukhtarah. And Allah knows best.
1255 — “If one of you lies on his back, he should not place one of his legs over the other.”
Al-Tirmidhi (2/127) narrated it: ʿUbayd ibn Asbat ibn Muhammad al-Qurashi narrated to us; my father narrated to us; Sulayman al-Taymi narrated to us, from Khidash, from Abu al-Zubayr, from Jabir, who said: The Messenger of Allah, peace and blessings be upon him, said it. He then said: “This hadith has been narrated by more than one person from Sulayman al-Taymi, but it is not known who this Khidash is.” Al-Tahawi also narrated it in Sharh al-Maʿani (2/360) through another route from al-Taymi, with the same wording.
I say: Al-Bazzar also narrated it in his Musnad (p. 249—its supplements): Qays ibn Adam narrated to us; my grandfather, Azhar ibn Saʿd, narrated to us, from Sulayman al-Taymi, from Khidash, from Abu al-Zubayr, from Jabir, from Ibn ʿAbbas, who said: The Messenger of Allah, peace and blessings be upon him, said it. He then said: “It has been narrated once (!) from Jabir, from the Prophet, peace and blessings be upon him. No one has said, ‘from Jabir, from Ibn ʿAbbas,’ except Azhar. Khidash was from Basra, and we know of no one who narrated from him besides al-Taymi and Muhammad ibn Thabit al-Basri; and he has been declared trustworthy.”
