13 - Muhammad ibn Bashshar narrated to us, Wahb ibn Jarir narrated to us, my father narrated to us, he said: I heard Muhammad ibn Ishaq narrating from Aban ibn Salih, from Mujahid, from Jabir ibn Abdullah, who said: The Prophet of Allah, peace and blessings be upon him, forbade us from facing the qiblah when urinating, but I saw him one year before he was taken (i.e., passed away) facing it.

6 - Chapter: How to uncover oneself when relieving oneself

14 - Zuhayr ibn Harb narrated to us, Waki' narrated to us, from al-A'mash, from a man, from Ibn Umar: that the Prophet, peace and blessings be upon him, when he wanted to relieve himself, would not raise his garment until he drew near to the ground. (2)

=============================================
And it was also recorded by Muslim (266) and Ibn Majah (322) via the chain of Yahya ibn Sa'id from him.
And it was recorded by al-Bukhari (148), Muslim (266), and al-Tirmidhi (11) via the chain of Ubaydullah ibn Umar, from Muhammad ibn Yahya ibn Habban from him.
And it is in the Musnad of Ahmad (4606), and Sahih Ibn Hibban (1418).

(1) Its chain is hasan. Muhammad ibn Ishaq explicitly stated that he heard it (tahdith) here and with Ahmad and others, so any suspicion of his tadlis is removed. He is truthful (saduq) with hasan hadith, and the rest of its narrators are trustworthy (thiqat). Jarir: he is Ibn Hazim al-Azdi al-Basri.
And it was recorded by al-Tirmidhi (9) and Ibn Majah (325) via the chain of Wahb ibn Jarir, with this same isnad, and he said: hasan gharib.
And it is in the Musnad of Ahmad (14872), and Sahih Ibn Hibban (1420).

(2) A hasan hadith, but this chain is weak due to the anonymity of the man narrating from Ibn Umar. There is disagreement regarding Waki' and al-A'mash concerning it:
- Waki' narrated it here with the anonymity of al-A'mash's shaykh, and it was narrated by al-Bayhaqi (1/96) from al-A'mash, from al-Qasim ibn Muhammad, from Ibn Umar. Al-Qasim ibn Muhammad: he is the son of Abu Bakr al-Siddiq, and he is trustworthy and a jurist.
- Waki' also narrated it, as did Abd al-Hamid ibn Abd al-Rahman al-Himmani — as al-Tirmidhi mentioned in his Jami' following hadith (14) — from al-A'mash, who said: Ibn Umar said. This is a disconnected (munqati') chain.
- And it is narrated from al-A'mash from Anas, and it will follow afterward.
