Al-Haythamī said: “Al-Ṭabarānī narrated it in al-Kabīr, and its narrators are trustworthy.” This is what he said, yet no one other than Ibn Ḥibbān deemed this Abū Shaybah trustworthy (1/306, Indian edition). Al-Dhahabī said: “It is not known who he is.” In sum, with its two corroborating reports, the hadith is good at the very least. And Allah Most High knows best.
I then found another route for the hadith of Muʿādh: al-Naḍr ibn Kathīr al-Saʿdī narrated to us from Yaḥyā ibn Saʿīd al-Anṣārī, from Saʿīd ibn al-Musayyib, from Muʿādh, with the same wording. It was recorded by al-Mukhalliṣ in al-Fawāʾid al-Muntaqāh (7/1/2). Its narrators are trustworthy, apart from this al-Naḍr, who is weak but devout, as stated in al-Taqrīb.
Note: Al-Suyūṭī included it in al-Jāmiʿ as cited above, attributing it to al-Ṭabarānī’s al-Awsaṭ. Al-Manāwī then claimed that this attribution had not been properly verified. He further stated that the wording in al-Awsaṭ is that of al-Kabīr, which does not contain: “And whoever has a good deed recorded for him with Him ...” It is as though, when he read al-Haythamī’s preceding statement, he failed to notice the words, “in al-Kabīr,” and thus fell into error. We ask Allah for protection from error.
2307 — “Whoever claims descent from someone other than his father will never smell the fragrance of Paradise, though its fragrance may be perceived from a distance of seventy years’ travel.”
It was recorded by Aḥmad (2/171/194) and al-Khaṭīb (2/347), through Shuʿbah, from al-Ḥakam, from Mujāhid, from ʿAbd Allāh ibn ʿAmr, from the Prophet, peace and blessings be upon him. I say: This is an authentic chain of transmission according to the conditions of al-Bukhārī and Muslim. Al-Ḥakam is Ibn ʿUtaybah al-Kūfī.
