and in this, he follows al-Bukhārī in "al-Tārīkh" (4/2/209). He did not refer to him as Abū Ṭuʿmah, nor did he make the slightest indication of this. Ibn Ḥibbān also followed them in this, mentioning him in "Thiqāt Atbāʿ al-Tābiʿīn" (7/575). Secondly, when they included him in "al-Kuná" as previously mentioned, they also did not indicate that he is the Hilāl whose biography was previously mentioned in (al-Asmāʾ). Thirdly, the careful observer of their biographies finds that they are not of the same generation. Whoever heard from Ibn ʿUmar would be a "tābiʿī," and whoever narrated from ʿUmar ibn ʿAbd al-ʿAzīz—who is a tābiʿī—would usually be from the followers of the tābiʿīn. Although this does not prevent him from being of the same generation, as it could be a case of peers narrating from each other, or at least the elders narrating from the younger ones. All of this is possible in my view, but the matter requires evidence. Therefore, I continued the investigation and research in this, especially since I have seen that later scholars have considered them one, and I found the following: Firstly, Imām Aḥmad said in "al-ʿIlal wa-Maʿrifat al-Rijāl" (1/295): "Abū Ṭuʿmah, this is a Shāmī, narrated by ʿAbd al-ʿAzīz ibn ʿUmar, and narrated by Ibn Jābir and Ibn Lahīʿah." He mentioned ʿAbd al-ʿAzīz ibn ʿUmar among those who narrated from Abū Ṭuʿmah, indicating that he is Hilāl himself, and this is supported by my statement: Secondly, I saw that Imām Aḥmad said in "al-Musnad" (2/25): Wakīʿ narrated to us: ʿAbd al-ʿAzīz ibn ʿUmar ibn ʿAbd al-ʿAzīz narrated from Abū Ṭuʿmah, their client, and from ʿAbd al-Raḥmān ibn ʿAbd Allāh al-Ghāfiqī that they both heard Ibn ʿUmar say: The Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) said:
