and Muṣʿab is considered lenient in ḥadīth as mentioned in "Taqrīb," where it is said: "He is in the fifth category." As for his father, Shaybah, he is the son of Jubayr ibn Shaybah ibn ʿUthmān al-Ḥajabī. They did not provide a biography for him, but rather for his great-grandfather: Shaybah ibn ʿUthmān. Despite this, al-Ḥāfiẓ mentioned in "al-Iṣābah" that Muṣʿab narrated from him, so this should be verified. It is possible that the phrase "from his father" is not preserved, which is why al-Bukhārī did not mention him as will be explained. And Allāh knows best. (See the correction number 313/8). The ḥadīth was attributed by al-Suyūṭī to al-Baghawī, al-Ṭabarānī, and al-Bayhaqī in "al-Shuʿab." Al-Munāwī quoted from al-Haythamī, who said: "Its isnād is good." If it is from this chain, then it is not good, which is the prevailing assumption. Al-Bukhārī included it in "al-Tārīkh" (4/1/352) through the chain of ʿAbd al-Malik ibn ʿUmayr from Ibn Shaybah from the Prophet (ṣallá Allāhu ʿalayhi wa-sallam) with the wording: "When one of you comes and his brother makes room for him, it is an honor that Allāh has bestowed upon him." He mentioned it in the biography of Muṣʿab ibn Shaybah, thus revealing another flaw in the ḥadīth, which is the issue of disconnection. This flaw was overlooked by al-Munāwī, following al-Suyūṭī, as he attributed it with this wording to al-Bukhārī in "al-Tārīkh" and al-Bayhaqī in "al-Shuʿab" from Muṣʿab ibn Shaybah. He did not say (disconnected) as is his habit in similar cases to avoid implying that he is a Companion. However, here he erred or forgot, and al-Munāwī said: "He indicated its goodness, and it includes ʿAbd al-Malik ibn ʿUmayr, whom al-Dhahabī mentioned in "al-Ḍuʿafāʾ" and said: Aḥmad said: His ḥadīth is inconsistent. Ibn Maʿīn: He is mixed up, but it is supported, so he meant it is good due to other factors." I found a corroborating narration from Ibn ʿUmar, elevated, with the wording: "When one of you comes to a group and they make room for him, let him sit, for it is an honor from Allāh that his Muslim brother has bestowed upon him. If they do not make room for him, let him look for the most spacious place and sit there." It was narrated by Abū Bakr al-Shīrāzī in "Sabaʿah Majālis min al-Amālī" (7/2) through the chain of al-Ḥākim Abū ʿAbd Allāh Muḥammad ibn ʿAbd Allāh al-Ḥāfiẓ and al-Khaṭīb in "al-Tārīkh."
