his back, he should not place one of his legs over the other."(1)(2)

This is a hadith narrated by more than one narrator from Sulayman al-Taymi, and this Khidash is not known who he is, and Sulayman al-Taymi narrated more than one hadith from him.

2972 - Qutaybah narrated to us, he said: al-Layth narrated to us, from Abu al-Zubayr, from Jabir, that the Messenger of Allah ﷺ forbade al-ishtimal al-samma' (wrapping oneself entirely in a garment without raising an edge), and al-ihtiba' (sitting on the heels while wrapping the arms around the legs) in a single garment, and that a man should raise one of his legs over the other while lying on his back(3).

This is a hasan sahih hadith.--------------------------------------------
(1) The wording of this hadith in copies (A) and (D) and the copy upon which al-Mubarakfuri commented reads: "from Jabir, that the Messenger of Allah ﷺ forbade al-ishtimal al-samma', and al-ihtiba' in a single garment, and that a man should raise one of his legs over the other while lying on his back." What we have established is from copies (L) and (S) and "Tuhfat al-Ashraf" 2/296, and it corresponds to the narration of Abu Ya'la, which he produced in his "Musnad" (2031) via the chain of Khidash from Abu al-Zubayr, with this isnad.
(2) A sahih hadith, and it was produced by Muslim (2099) (74), Abu Dawud (4865). It is in "Musnad Ahmad" (14198), and "Sahih Ibn Hibban" (5551).
It will come within the following hadith, and its takhrij will come there.
(3) Its isnad is sahih, and it was produced in full by Muslim (2099), and it is in "al-Musnad" (14452), and "Sahih Ibn Hibban" (5553).
It was produced without its final section by Abu Dawud (4081), and al-Nasa'i 8/210. As for the final section alone, its takhrij has already preceded in the previous hadith.
