and both of them. For he attributed it in "al-Jāmiʿ al-Kabīr" (1/210/2) to both of them and to Abū ʿAwānah from the ḥadīth of Abū Saʿīd. And this is correct as will become clear to you from this referencing.

"Indeed, Allāh has vessels among the people of the earth, and the vessels of your Lord are the hearts of His righteous servants, and the most beloved of them to Him are the softest and most tender." It was narrated by al-Ṭabarānī in "al-Muʿjam al-Kabīr" (Q 40/1 - al-Muntaqá minhu): Jaʿfar ibn Muḥammad al-Firyābī told us, saying: Isḥāq ibn Rāhwayh told us, saying: Baqiyyah ibn al-Walīd informed us, saying: Muḥammad ibn Ziyād narrated to me from Abū ʿAnbah al-Khawlānī, raising it to the Prophet (ṣallá Allāhu ʿalayhi wa-sallam): and he mentioned it. I said: And this isnād is strong, all its men are trustworthy and reliable except Baqiyyah, who is truthful but often conceals his sources from the weak as the ḥāfiẓ said, and here he has explicitly stated the narration, thus we are safe from his concealment. Therefore, the ḥāfiẓ al-ʿIrāqī said in "Takhrīj al-Iḥyāʾ" (2/154): "It was narrated by al-Ṭabarānī and its isnād is good." And he said in another place (3/13): "In it is Baqiyyah ibn al-Walīd, who is a concealer, but he explicitly stated the narration." Therefore, al-Haythamī said, as quoted by al-Munāwī and approved by him: "The isnād is ḥasan." Abū Muṭīʿ al-Aṭrābulusī disagreed, saying: from Muḥammad ibn Ziyād with it mawqūf. It was narrated by Abū Ṭālib al-Makkī al-Muʾadhdhin in "Ḥadīthuh" (Q 230/2) and al-Ḍiyāʾ al-Maqdisī in "al-Muntaqá min Ḥadīth Abī ʿAlī al-Awqī" (1/2). But this Abū Muṭīʿ, whose name is Muʿāwiyah ibn Yaḥyá, is truthful but has errors, so the narration of Baqiyyah is more reliable, and it has a supporting narration from the ḥadīth of Abū Umāmah, raised similarly. However, it is very weak
