I say: This is a weak chain of transmission. Its narrators are trustworthy apart from this ʿĪsā. Ibn Abī Ḥātim said (3/1/285): “My father was asked about him, and he said: ‘Weak.’” As for Ibn Ḥibbān, he mentioned him among the trustworthy narrators. This is the basis for al-Haythamī’s statement (10/231): “Al-Ṭabarānī narrated it, and its chain consists of narrators of the Ṣaḥīḥ, apart from ʿĪsā ibn Mūsā ibn Īyās ibn al-Bukayr, who is trustworthy!”
Moreover, there is a break in the chain between Ṣafwān and Anas. Abū Ḥātim said: “Ṣafwān did not see Anas, and his narration from him is not sound.” Abū Dāwūd said: “He did not see any of the Companions except Abū Umāmah and ʿAbd Allāh ibn Busr.”
Yet in my view the hadith is good. Al-Haythamī cited, as supporting evidence for its first part, a hadith from Muḥammad ibn Maslamah, attributed to the Prophet, with the wording: “Indeed, your Lord has breezes of grace during the days of your lives, so avail yourselves of them; perhaps one of you will receive a breeze from them after which he will never be miserable.” He said: “Al-Ṭabarānī narrated it in al-Awsaṭ and al-Kabīr with similar wording. Its chain contains narrators whom I did not recognize, while those whom I did recognize were declared trustworthy.”
The remainder of it—the passage concerning concealment—has supporting evidence in a hadith from Abū Hurayrah, attributed to the Prophet, with the same wording. Al-Kharāʾiṭī narrated it in Makārim al-Akhlāq, as cited in al-Jāmiʿ al-Kabīr (2/49/1).
