“Its isnād is sound,” and al-Dhahabī concurred.

That is what they both declared. As for Mūsā ibn Yaʿqūb al-Zamaʿī, al-Taqrīb describes him as “trustworthy but prone to poor retention,” yet he is not the only one who related this report, as will be shown; therefore, the ḥadīth is strong.

Abū Dāwūd and al-Ḥākim add in one version: Mūsā ibn Yaʿqūb said, “Razq ibn Saʿīd ibn ʿAbd al-Raḥmān al-Madani also narrated it to me from Abū Ḥāzim, and he added: ‘and at the time of rainfall.’”

This Razq is classed as unknown (majhūl) in al-Taqrīb, so do not be deceived by al-Shawkānī’s remark in Tuḥfat al-Dhākirīn—after he cited the report with this addition from Abū Dāwūd—stating: “Al-Ṭabarānī in al-Kabīr, Ibn Mardawayh, and al-Ḥākim also recorded it, and it is a sound ḥadīth.”

Indeed, this extra clause appears in other aḥādīth; see our notes on al-Targhīb.

The ḥadīth was further transmitted by Ibn Ḥibbān and Ibn Khuzaymah in their Ṣaḥīḥ collections, as recorded in al-Targhīb and in al-Talkhīṣ. Mālik narrated it in the Muwaṭṭaʾ, and from him al-Bukhārī in al-Adab al-Mufrad, through Abū Ḥāzim, as a mawqūf report from Sahl with the wording: “Two moments during which the gates of heaven are opened, and scarcely is any supplicant turned back: at the announcement of the prayer call and when the ranks are arrayed in the path of Allah.”

Ibn ʿAbd al-Barr said: “This narration is mawqūf in the Muwaṭṭaʾ according to several transmitters, and such a statement is not uttered on the basis of personal opinion. It was also reported by Ayyūb ibn Suwayd and Muḥammad ibn Mukhlad.”
